on a number of plug-in programs, so it can be expanded easily with new test and data collection plug-ins.
The ADS794xEVM-PDK is controlled by a plug-in running in ADCPro. For more information about
ADCPro, see the ADCPro™ Analog-to-Digital Converter Evaluation Software User's Guide (literature
number SBAU128), available for download from the TI web site.
This manual covers the operation of both the ADS794xEVM and the ADS794xEVM-PDK. Throughout this
document, the abbreviation EVM and the term evaluation module are synonymous with the ADS794xEVM.
Operation of the EVM and kit for both the ADS7946 and the ADS7945 devices is identical, unless
otherwise noted.
1.2
Introduction
The ADS794xEVM is an evaluation module built to the TI Modular EVM System specifications. It can be
connected to any modular EVM system interface card.
The ADS794xEVM is available as a stand-alone printed circuit board (PCB) or as part of the
ADS794xEVM-PDK, which includes an MMB0 motherboard and software. As a stand-alone PCB, the
ADS794xEVM is useful for prototyping designs and firmware because it offers circuitry that meets the
product data sheet specifications of either the ADS7946 or ADS7945 devices.
The ADS7945 and ADS7946 are 14-bit, 2-MSPS ADCs with fully differential and pseudo-differential
unipolar inputs, respectively. These devices operate at a 2-MSPS sample rate with a 16-clock SPI data
frame that features both outstanding dc and excellent dynamic performance. These devices also include a
two-channel input multiplexer and a low-power SAR ADC with an inherent sample-and-hold (S/H) input
stage. During normal operation at 2 MSPS, the ADS794x dissipates a mere 11.6 mW.
Note that the ADS794xEVM has no microprocessor and cannot run software. Therefore, some type of
interface is required to connect the ADS794xEVM to a computer. In the ADS794xEVM-PDK kit, the MMB0
motherboard serves as the interface between the computer and the ADS794xEVM board.

Analog Interface
The ADS794xEVM is designed for easy interfacing to multiple analog sources. SMA connectors allow the
EVM to have input signals connected via coaxial cables. In addition, the Samtec connector provides a
convenient 10-pin, dual-row, header/socket combination at P2. This header/socket provides access to the
analog input pins of the ADS794x. Consult Samtec at http://www.samtec.com or call 1-800-SAMTEC-9 for
a variety of mating connector options. All analog inputs are buffered by OPA836 high-speed operational
amplifiers in order to properly drive the ADS794x ADC inputs.
Use appropriate caution when handling these pins. Table 2 summarizes the pinout for analog interface P2.

ADS794xEVM Analog Inputs with ADS7945 Installed
Each channel of the ADS7945 uses two OPA836 operational amplifiers to drive the fully differential inputs.
The input signals can be applied to either the SMA or P2 header connectors. These operational amplifiers
offset the input signal to use an inverting configuration with a single supply. The EVM Operation section
explains in detail how this offset is used to allow bipolar signals for the ADS7945 with jumper J6.

Serial Interface (SPI)
The ADS794x ADC uses SPI serial communication in mode 0 (CPOL = 0, CPHA = 0). Because the serial
clock (SCLK) frequency can be as fast as 40 MHz, the ADS794xEVM offers 47-Ω resistors between the
SPI signals and P1 to aid with signal integrity. Typically, in high-speed SPI communication, fast signal
edges can cause overshoot; these 47-Ω resistors slow down the signal edges in order to minimize signal
overshoot.
3.2
ADS794x Channel Select as SDI (MISO)
The ADS794x ADC offers direct control over the internal multiplexer using pin 11. The ADS794xEVM uses
a flip-flop (see U9 in the attached schematic) to convert this pin into a typical SPI SDI (MOSI) pin. This
architecture takes advantage of the SPI full-duplex data transmission sequence to control channel
selection at the same time conversion data are acquired. The digital word 0x000 can be used to select
channel 0, and the word 0xFFFF can be used to select channel 1.
3.3
I2C Bus for Onboard EEPROM
The ADS794xEVM has an I2C bus to communicate with the onboard EEPROM that records the board
name and assembly date. It is not used in any form by the ADS794x converter.

Digital Power Options
The ADS794xEVM uses a jumper in J3 to connect the digital power supply to either +3.3 VD (P3.10) or +5
VD (P3.9). J3 in position 1-2 connects the digital power supply to +5 VD; position 2-3 connects the digital
power supply to +3.3 VD. Without a jumper in J3, the digital power supply can be connected to +1.8
VD(P3.7) with a jumper wire to pin J3.2. The jumper in J3 must always be in position 2-3 (+3.3 VD) while
using the MMB0 with the EVM.
4.3
Reference Voltages
The ADS794xEVM uses a jumper in J2 to select between the internal (REF5040) and external voltage
reference sources. J2 in position 1-2 selects the internal reference; position 2-3 selects the external
reference. The selected reference is cleaned with a RC filter and buffered with a OPA350 operational
amplifier.
CAUTION
Digital supply and reference voltage must be at or below the analog supply
voltage at all times.

EVM Operation
This section provides information on the analog input, digital control, and general operating conditions of
the ADS794xEVM without the MMB0 motherboard. Software operation is presented in Section 7.
5.1
Analog Input
The ADS794xEVM offers three different analog input modes, selectable with jumper J6 and the type of
input signal. Note that the ADS794x converter by itself only allows dc-coupled unipolar signals. The two
additional input modes are available because OPA836 operational amplifiers drive the analog inputs. It is
preferable for external signal drivers or filters to have low output impedance to reduce gain errors.
Mode 1: DC-Coupled Unipolar Inputs (J6 Closed)
DC-coupled unipolar signals are typically produced by single-supply signal drivers. To allow dc-coupled
unipolar signals, J6 should be closed. This mode allows an input signal range from 0 V to VREF for all EVM
analog inputs. In this mode, the voltage read at the ADC is equal to (VREF – VIN).
Mode 2: DC-Coupled Bipolar Inputs (J6 Open)
DC-coupled bipolar signals are typically produced by dual-supply signal drivers. To allow dc-coupled
bipolar signals, J6 should be open. This mode allows an input signal range from –VREF/2 to +VREF/2 for all
EVM analog inputs. In this mode, the voltage read at the ADC is equal to (VREF/2 – VIN).
Mode 3: AC-Coupled Inputs (J6 Closed)
AC-coupled signals are typically produced by high-pass filters. To allow ac-coupled bipolar signals, J6
should be closed. This mode allows an input signal range from –VREF/2 to +VREF/2 for all EVM analog
inputs. In this mode, the voltage read at the ADC is equal to (VREF/2 – VIN).
5.2
Digital Control
The digital control signals can be applied directly to the P1 header (top or bottom side). The modular
ADS794xEVM can also be connected directly to a DSP or microcontroller interface board, such as the 56K Interface or HPA-MCU Interface boards available from Texas Instruments, or the MMB0 if purchased
as part of the ADS794xEVM-PDK. For a list of compatible interface and/or accessory boards for the EVM
or the ADS794x, see the relevant product folder on the TI web site.

www.ti.com
Powering Up the ADS794xEVM-PDK
Once the ADS794xEVM-PDK kit is configured, power can be applied to the MMB0. This power comes
from an external supply that delivers +6 VDC to the MMB0 using the included CA-2186 cable via J2 on
the MMB0 motherboard. No wall power supply is included with the PDK; an external power supply should
be connected via the included CA-2186 cable where Figure 8 indicates.
Figure 8. Powering Up ADS794xEVM-PDK
After the power supply is connected, four green LEDs in the bottom right-hand corner of the MMB0
motherboard should light up. If these LEDs do not light up, disconnect the power and verify that J12 is
closed.
6.5
First-Time Connection: ADS794xEVM-PDK to PC, Completing Driver Installation
The first time that the ADS794xEVM-PDK kit is connected to the PC via USB, the PC prompts the user for
two drivers. At this point, it is presumed that the ADCPro software and the ADS794xEVM plug-in have
been installed, and that the ADS794xEVM-PDK kit is properly configured and powered up (refer to
Section 6.1 through Section 6.4). The following sections show how to install these drivers.
NOTE: Driver prompts may not appear if another PDK kit has been used on the PC before.

ADS794xEVM-PDK Kit Operation
The evaluation software is based on ADCPro. This program operates using a variety of plug-ins. 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.
The following sections describe how to use ADCPro and the ADS794xEVM plug-in to acquire data.
7.1
About the MMB0
The MMB0 provides the USB interface between the PC and the ADS794xEVM. The MMB0 is a modular
EVM system motherboard. It is designed around the TMS320VC5507, a DSP with an onboard USB
interface from Texas Instruments. The MMB0 also has 16 MB 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.
7.2
Loading the ADS794xEVM-PDK Plug-in
The ADS794xEVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS794x.
You can adjust the ADS794xEVM 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 ADS794xEVM plug-in, the setting immediately updates on the board.
Settings on the ADS794xEVM correspond to settings described in the ADS794x product data sheet
(available for download at http://www.ti.com); see the product data sheet for details.
To load the ADS794xEVM plug-in, follow these steps.
Step 1. Make sure the PDK kit is configured and powered up as explained in Section 6.3 and
Section 6.4. Then, press the Reset button on the MMB0 (in the top right-hand corner) once to
clear the board memory.
Step 2. Start ADCPro from the Windows Start menu.
Step 3. Load the ADS794xEVM plug-in from the ADCPro drop-down EVM menu; see Figure 10. Note
that only one EVM plug-in can be loaded at a time. If a different plug-in is selected, the
previous plug-in is unloaded.
Step 4. When the plug-in is loaded, the plug-in searches for the board. A series of messages in the
status area will indicate this action, eventually showing Select Device...
The plug-in is now loaded and ready to work with the ADS794xEVM.
