Introduction
The ADS1672EVM is an evaluation module built to the TI Modular EVM System specification. You can
connect the ADS1672EVM to any Modular EVM System interface card.
The ADS1672EVM is available as a stand-alone printed circuit board (PCB) or as part of the
ADS1672EVM-PDK, which includes an MMB0 motherboard and software. As a stand-alone PCB, the
ADS1672EVM is useful for prototyping designs and firmware development.
Note that the ADS1672EVM cannot run software. To connect it to a computer, some type of interface is
required.

Analog Interface
The ADS1672EVM board applies 5V of power (VCC) to the ADS1672 (U6) and THS4520 (U2). The
THS4520, a wideband, fully-differential amplifier, drives the differential inputs of the ADS1672. This device
was selected because of its slew rate (570V/μs), settling time (7ns to 0.1%), low noise (2nV/√Hz) and low
harmonic distortion (HD3: –123dBc at 100kHz).

Analog Interface
www.ti.com
Analog input signals to the THS4520/ADS1672 signal chain can be applied at connectors J1 (inverting
input, –IN) and J2 (noninverting input, +IN) or P3-1 (–IN) and P3-2 (+IN). The P3 connector is an SMT
plug on the top side of the PCB (as Figure 1 shows). The signal at +IN and –IN should be differential and
centered at 2.5V.
Figure 1. Location of Onboard Connectors J1, J2, W1, P1, P2, SW1, and P3
At the analog board inputs, +IN and –IN, there are termination resistors (R3, R6 = 49.9Ω) installed on the
board at J1 and J2 (as Figure 2 illustrates). These resistors are followed by a capacitor between the inputs
(C55 = 750pF) and resistors (R8, R10 = 383Ω) to the THS4520. Additional pads are available at the
inputs of the THS4520 to allow insertion of capacitor and/or resistor networks.

Analog Interface
www.ti.com
Following the THS4520, an R-C network connects directly to the ADS1672. This R-C network (R56, R15,
C18, R55, and R14) acts as a first-order, anti-aliasing filter for the ADS1672. The corner frequency of the
installed first-order filter is 1/[2π × (10Ω + 10Ω) × 750pF] or 10.6MHz. Pads are available to install more
resistors and capacitors, as needed.
The common-mode voltage to the THS4520 is set at RCM and can be connected to the analog board
inputs +IN and –IN through R53 and R54 as shown in Figure 2. The output signal from the onboard
REF5025 (U3) establishes this voltage at 2.5V. You can inject an external common-mode voltage into the
THS4520 through P3-15 (as Table 1 shows). If this option is used, the shunt on W1 (an onboard jumper)
must be moved to position 2-3 (see Figure 1). With this reconfiguration, RCM in the input circuitry does not
change, as shown in Figure 2. If the common-mode of the input signals center at a voltage other than
VCC/2, pull-up resistors (R48 and R49) must be installed to maintain the proper input common-mode
range to the THS4520 amplifier. The THS4520 performance degrades if operated beyond its specified
range of 1.2V to 4.25V (when powered with 5V).
Samtec part number TSM-110-01-T-DV-P provides a convenient 20-pin, dual-row, header/socket
combination at P3. As shown in Figure 1, the P3 header provides access to –IN and +IN of the
ADS1672EVM board as well as the common-mode pins of the THS4520 (pins 4 and 9, CM). Consult
Samtec at http://www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector options.
There is no filtering or protection on the P3 pins. Use appropriate caution when handling these pins.

Reference Buffer

www.ti.com
Reference Buffer
The ADS1672 reference pins have switched capacitor inputs. At a clock rate of 20MHz (X1), a charge
injection in and out of the ADS1672 reference input occurs. The external reference voltage that drives the
ADS1672 reference pin must settle in less than 50ns. The REF5030 (U1) generates the 3.0V reference
signal (Figure 3). The output of the REF5030 is heavily filtered to remove noise. The onboard OPA211
(U4) again filters and buffers the reference signal so that the reference signal noise to the ADS1672 is
less than the noise generated by the converter itself. The OPA211 is a low-noise, unity-gain stable
amplifier that provides a reliable current source for the ADS1672 reference input. The OPA211 and output
decoupling capacitors work together to settle the VREFP (ADS1672) reference input voltage to within ±1/2
LSB, every 50ns. This board uses a 22μF ceramic capacitor with a 0.1μF ceramic capacitor directly
across the reference inputs, VREFP and VREFN. Note that the 22μF and 0.1μF capacitors are placed as
close to the ADS1672 reference pins as possible. These capacitors further reduce noise that is common
to both inputs. The ADS1672 VREFN pin goes to ground.

Digital Interface
It is easy to interface the ADS1672EVM board to multiple control platforms. The P2 connector (Figure 4,
Samtec part number SSW-110-22-S-D-VS) provides a convenient digital access to the key ADS1672 I/O
pins. Consult Samtec at http://www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector
options.
SW1, a 10-position DIP switch (Figure 4), gives users the ability to change the setting of the ADS1672
digital configuration pins when the EVM is used as a stand-alone evaluation board. Pull-up/-down resistors
are provided to set the static state of the digital configuration pins. All position settings for SW1 must be
off (factory default state) when the board is configured for use with ADCPro. The ADCPro software uses
the PCS9535 at U5, a remote I2C I/O expander at address 32 (20h), to control the configuration pins. In
addition, the pin setting for the SW1 switches must be off when using the I2C function for stand-alone
systems. The ADS1672EVM does not support LVDS interface mode; only the standard 3.3V CMOS
interface is supported.

Clock Source
You can either select the onboard 20MHz crystal oscillator as the master clock for the ADS1672, or apply
an external clock signal through J3. When the onboard 20MHz clock is used, the W2 jumper must be
installed (Figure 5). W2 is an enable function for the onboard crystal oscillator (X1). W3 in positions 1-2
sends the onboard clock to the DUT by way of the buffer, U8. When using an external clock, move the W3
jumper (see Figure 4 and Figure 5) on pins 1-2 to cover pins 2-3, and remove the W2 jumper (see
Figure 6) to disable X1. Then apply your clock source to J3. Otherwise, simply remove the jumper when
an external clock is inserted at J3.

Use as a Stand-Alone EVM
The ADS1672EVM can be used as a stand-alone EVM, provided that the proper control signals are
applied to serial input connector P2 (top or bottom side). The required power supplies (+5VA and +3.3VD)
can be connected directly to J4 pins 3 and 9 or test points TP5 and TP7, respectively. Both supplies are
referenced to J4 pin 6 or TP8, and should be sourced from clean, well-regulated lab supplies for best
performance. The minimum control lines necessary are the active-low chip select (CS) and START inputs,
which are applied to P2 pins 1 and 7. If an external serial clock is desired, the signal is applied to P2 pin
5. The ADS1672 digital configuration pins can be set statically by using SW1, or can be manipulated
through U5 by an I2C controller connected to P2 pins 16 and 20 (all SW1 positions must be set to off when
using U5). For additional details, please see section Section 9 of this document and review the ADS1672
datasheet.

EVM Operation
This section provides information on the analog input, digital control, and general operating conditions of
the ADS1672EVM.
9.1
Analog Input
The differential analog input to the ADS1672EVM board is applied through J1 (–IN) and J2 (+IN) or P3.1
(–IN) and P3.2 (+IN).
9.2
Digital Control
The digital control signals can be applied directly to P2 (top or bottom side). The modular ADS1672EVM
can also be connected directly to a DSP or microcontroller interface board, such as the 5-6K Interface
EVM or HPA-MCU Interface boards available from Texas Instruments. For a complete list of compatible
interface and/or accessory boards for the EVM or the ADS1672, see the relevant product folder on the TI
web site.
Some of the digital signals to the ADS1672 are controlled using three methods: SW1 slide switches, GPIO
pins through P2.17 (W4 configured to GPIO), or I2C control using U5.
You can access a general-purpose input/output (GPIO) port through P2.17 by also connecting W4.2
(START) to W4.3 (GPIO), as shown in Figure 7. Otherwise, for proper ADCPro operation, pin 1 (FSX) is
connected by a jumper to pin 2 (START).

ADS1672EVM-PDK Power Supply
The ADS1672EVM can be powered with the J4 connector or by attaching the MMB0 board. The MMB0
board provides the 5-V and 3.3-V power to the ADS1672EVM. Because the circuitry is provided on the
ADS1672EVM, the complete system can be powered by an external AC adapter (not included) that meets
the following requirements:
• Output voltage: 5.5 VDC to 15 VDC
• Maximum output current: ≥ 500 mA
• Output connector: barrel plug (positive center), 2.5-mm I.D. × 5.5-mm O.D. (9-mm insertion depth)
• Complies with applicable regional safety standards

About the MMB0
The MMB0 is a Modular EVM System motherboard. It is designed around the TMS320VC5507, a DSP
from Texas Instruments that has an onboard USB interface. The MMB0 also has 16MB of SDRAM
installed.
The MMB0 is not sold as a DSP development board, and it is not available separately. TI cannot offer
support for the MMB0 except as part of an EVM kit. For schematics or other information about the MMB0,
contact Texas Instruments.
11.1 Connecting the Power Supply
The ADS1672EVM-PDK can be operated with a unipolar +5V supply.
When the MMB0 DSP is powered properly, LED D2 glows green. The green light indicates that the 3.3V
supply for the MMB0 is operating properly; however, it does not indicate that the EVM power supplies are
operating properly.
11.1.1
Connecting an AC Adapter
An AC adapter can be connected to barrel jack J2 on the MMB0. J2 is located next to the USB connector.
The adapter must output 6V to 7V dc. The connector must be sleeve-negative, tip-positive and it should
have a current rating of at least 500 mA.
Jumper J12 on the MMB0 connects a wall-mounted power supply to the board. To use the wall-mount
supply, J12 must be shorted. Figure 11 illustrates how to connect an ac adapter to the MMB0.

Evaluating with the ADCPro Software
The evaluation software is based on ADCPro, a program that operates using a variety of plug-ins. The
ADS1672EVM plug-in is installed as described in Section 11.2, Running the Software and Completing the
Driver Installation.
To use ADCPro, load an EVM plug-in and a test plug-in. To load an EVM plug-in, select it from the EVM
menu. To load a test plug-in, select it from the Test menu. To unload a plug-in, select the Unload option
from the corresponding menu.
Only one of each type of plug-in (EVM and Test) can be loaded at a time. If you select a different plug-in,
the previous plug-in is unloaded.
12.1 Using the ADS1672EVM-PDK Plugin
The ADS1672EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS1672. It
consists of a tabbed interface (see Figure 14), with all of the functions available on the main tab. The
controls on the main tab are described in this section.
You can adjust the ADS1672EVM settings when you are not acquiring data. During acquisition, all
controls are disabled and settings may not be changed.
When you change a setting on the ADS1672EVM plug-in, the setting is immediately updated on the board.

Evaluating with the ADCPro Software
www.ti.com
Settings on the ADS1672EVM correspond to settings described in the ADS1672 data sheet; see the
ADS1672 data sheet (available for download at the www.ti.com) for details.
Because the effective data rate of the ADS1672 depends on settings of the Modulator Clock and the
operating modes of FPATH, LL_CONFIG, and the Data Rate Bits, the Data Rate indicator (in the upper
right corner of the plug-in interface) is always visible and updated whenever a setting is changed that
affects the data rate.
12.1.1
Settings Tab
The FPATH control (illustrated in Figure 20) can configure the ADS1672 digital filter as a Wide-Bandwidth
Filter or Low-Latency Filter setting.
Figure 20. FPATH settings
The LL_CONFIG control can configure the ADS1672 in a Single Cycle Settling mode or Fast Response.
Figure 21 shows the LL_CONFIG options.
Figure 21. LL_CONFIG Settings
The Data Rate Bits can be configured as 00b, 01b, 10b, or 11b. Figure 22 shows the Data Rate Bits
options.
Figure 22. Data Rate Bits Setting Options
The Modulator Clock can be configured to match the onboard oscillator (20MHz) or the external clock. The
setting of the Modulator clock in ADCPro will change the Data Rate indicator in the top right corner of the
plug-in interface. The Post Averages option is used to average the data output results after data have
been collected. Figure 23 shows the Modulator Clock and Post Averages options.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
