Software
Once the ADS1271EVM-PDK software (described in Step 4) is installed, evaluation and development with
the ADS1271 can begin.
4.1
Basic Usage
Once the evaluation software is started, it checks to see whether an MMB0 is connected. If hardware is
connected and recognized, the program downloads the firmware to it, and continues to operate. If no
hardware is detected, a dialog box is displayed telling you that it cannot find an MMB0. If you see this,
make sure the MMB0 is connected and powered on and click Retry. If the software cannot find the
hardware, you can click Cancel to quit the application.
After the program loads the MMB0 successfully, you will see a screen similar to that shown in Figure 2.
The top portion of the display shows an FFT of the ADC data and certain AC analysis numbers.
Immediately below the FFT graph (middle portion of the display) are a number of controls and meters. At
the bottom of the display is a set of tabs, which show either a histogram, a picture of the incoming
waveform, or the data recording controls.
To exit the program, select File → Exit from the menu bar.
When the program starts, it will be in idle mode. You can put it in either Acquire Mode or Record Mode.
4.1.1
Acquire Mode
In Acquire mode, the ADS1271EVM software collects data from the board in 2,048-sample blocks and
performs the appropriate analysis. Both AC and DC analyses are performed.
To put the program into Acquire mode, click the Acquire button.
In Acquire mode, you can only view the data from one channel at a time. To choose channels, use the
Channel box.
4.1.1.1
AC Analysis
The basic AC analysis consists of the FFT graph and THD calculations. The THD analyzer uses an
automatic tone-detection algorithm, which searches for the highest harmonic to use for the THD analysis.
The detected frequency is shown in the indicator marked Tone Freq.
NOTE: For the THD analysis to work, the input must be a sine wave below half the Nyquist
frequency, since the THD analyzer needs at least one harmonic for correct operation.
4.1.1.2
Time Domain Analysis
The ADC data is plotted as a waveform in the time domain on the Waveform tab located at the bottom of
the screen.
4.1.1.3
DC Analysis
For DC analysis, the middle section of the application provides DC RMS noise (standard deviation), peak
amplitude, and a DC level meter.
A histogram of the ADC data is plotted on the Histogram tab located at the bottom of the screen. Basic
DC measurements work best when the ADC is driven by an amplifier, stable voltage source, or by shorting
the inputs.
4.1.2
Record Mode
To record/save ADC data, go to the Record To File tab and do the following:
1. If Acquire is on, turn it off. You must stop acquisition before the record feature can be enabled.
2. Enter acquisition settings using the Conversion Mode drop-down control and Sample Rate field. The
Channel selector can be ignored since it has no effect during data recording.

3. Enter a path in the Destination File field. You can use the folder icon to browse for the file with a
standard file dialog. If the file you enter cannot be opened or created, the record button will be
disabled. If the path points to an existing file, the file will be overwritten when you activate recording.
4. Enter the number of ADC samples to record to the file. You can enter this in time duration or number
of samples; the controls will update automatically to match. The number of samples is limited by
available memory on the MMB0 to a minimum of 2048 samples and a maximum of approximately
2,700,00 points.
5. Click the Record button. You will see the Samples Retrieved bar graph increase. When it reaches the
number of samples you selected, recording will stop and the record button will be turned off.
The data file is a comma-separated values (CSV) file containing comma-delimited decimal ADC values.
The first data column is Channel 1 followed by Channel 2. The data file can be imported into a
spreadsheet for future inspection and analysis.
4.2
Configuration
Sample rate and conversion mode are set to the same for both ADS1271 devices on the EVM.
The three ADS1271 conversion modes are selectable from the drop-down control, Conversion Mode.
The ADS1271 clock is generated by a PLL synthesizer on the MMB0. The synthesizer will generate a
clock/data rate that is as close as possible to the requested frequency, but the data rate may be slightly
different.
The data rate is limited for each of the possible device modes. For high-speed mode, the maximum data
rate is approximately 105kSPS. For other modes, it is approximately 52.5kSPS. The application will
automatically reduce the data rate to the maximum allowed for that mode that is selected.

Analog Interface, J1, J4, and J5
The ADS1271EVM features several analog input options. Signals can be routed directly to the converters
or can pass through the onboard buffer amplifiers (U5, U6). Signals can be applied to the board through
the standard modular EVM analog connector (J1) or brought in through the auxiliary input connectors (J4,
J5). A set of switches selects which analog connector source is used and whether the buffer amplifiers are
in the signal path. These switches enable several configurations for evaluation. Switch operation and
analog path configuration are described in Section 5.2.2, Table 6 , and Table 7.
For maximum flexibility, the ADS1271EVM is designed for easy interfacing to multiple analog sources.
Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin, dualrow, header/socket combination at J1. This header/socket provides access to the analog input pins of the
ADS1271.

ADS1271EVM Hardware Details
5.2.2.1
www.ti.com
Buffer Amplifiers
The buffer amplifiers on this EVM are OPA1632s (U5, U6). These amplifiers are optimized for ac
performance and are configured as fully-differential unity gain buffers. They require ±15V supplies, which
are provided from J3 pins 1 and 2.
The OPA1632 requires a common-mode voltage, which is provided on this EVM by U2 and U3. Some
users may not wish to use the buffer amplifier section and provide the ±15V supplies. If the ±15V supplies
are not connected, then having a voltage on the VOCM pins of the amplifiers would exceed their maximum
ratings. Thus, U2 and U3 provide a separate 2.5V reference for the buffer amplifier section rather than
using the same reference as the ADS1271, which would always be powered. For this reason, U2 and U3
power is provided through a separate regulator, U11.
5.3
Digital Interface, J2
The ADS1271EVM is designed to easily interface with multiple control platforms. Samtec part numbers
SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin, dual-row, header/socket
combination at J2. This header/socket provides access to the digital control and serial data pins of the
ADS1271.
Because the ADS1271 devices are capable of daisy-chaining, this EVM has been designed to permit
stacking; up to four EVMs can be stacked, allowing for eight devices to be placed in a signal chain. To
accommodate stacking of EVMs, J2 has some different connections on the top and the bottom side of the
board. Differences between top and bottom connectors are highlighted in Table 10.

When power is supplied to J3, J6 allows for either 3.3V or 1.8V to be applied to the digital sections of the
ADS1271. J6 also provides for a method of measuring AVDD and DVDD supply currents if the shunts on
J6.1-2, J6.3-4, J6.5-6, and J6.7-8 are removed and a current meter is connected between the appropriate
pins. See the schematic and printed circuit board silkscreen for details.
5.4.1
ADC Power
Power for the ADS1271 analog supply voltage (AVDD) comes from +5VA, which is supplied through J3.3.
The shunt from J6 pins 1 to 2 applies this supply to the U7 ADS1271 device, while the shunt from J6 pins
5 to 6 applies this supply to the U8 ADS1271.
The ADS1271 digital supply voltage (DVDD) is selected using J6. When a shunt is applied from J6 pins 9
to 10, +1.8VD is selected, and this power comes from J3.7. If a shunt is placed from J6 pins 11 to 12 (the
default factory setting), +3.3VD is selected, which is provided from J3.9. J6 pins 13 and 15 provide a
means of connecting analog and digital grounds to the EVM; these grounds come from J3.6 and J3.5,
respectively. These grounds are always connected together at the EVM.
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
ADS1271 data sheet before applying power to the EVM.
CAUTION
Note that a shunt should only be connected between J6 pins 9 and 10 OR pins
11 and 12, but never both; doing so would short the +3.3V supply to the +1.8V
digital supply.
5.4.2
Stand-Alone Operation
When used as a stand-alone EVM, the analog power can be applied to J6.2 and J6.6, referenced to
J6.13. DVDD can be applied to J6.4 and J6.8, referenced to J6.15.

Reference Voltage
The ADS1271 requires an external voltage reference. Two switches, S3 and S5, select the source of the
reference for the two ADS1271s on the EVM. An external reference may be supplied through J1 pin 20 on
the ADS1271EVM, or through J4 and J5, the auxiliary analog input connectors. A 2.5V reference is
provided on the EVM for convenience. These different reference sources can be selected using S3 and
S5, as shown in Table 12.
CAUTION
Verify that the external reference voltage is within the safe operating limits
shown on the ADS1271 data sheet before applying power to the EVM.

Communication Modes
The ADS1271EVM has a digital routing network which can help simulate several possible system
connections. The routing network also provides level-shifting, which allows the ADS1271 to be operated at
any supported logic level regardless of the logic level used on J2. Note that you are not required to include
this circuitry in your own designs; typically no glue logic is required to connect one or more ADS1271s to a
processor.
5.6.1
Digital Signal Routing Control
Routing is controlled by pins CLKRMODE, CLKXMODE, and OBCLKSEL on J2.
5.6.1.1
CLKR Routing
CLKRMODE controls the direction and connection of CLKR. When CLKRMODE is low, CLKR is an input
connected only to SCLK. When CLKRMODE is high, CLKR becomes an output connected to SCLK, and
SCLK is tied to CLK. This connection can be useful in both FSYNC and SPI modes.
A pull-down resistor is installed on CLKRMODE, making FSYNC mode the default setting.

SCLK (SCLK tied to CLK)
CLKX Routing
When CLKXMODE is high, CLKX is an output connected to CLK. This setting is primarily useful for certain
configurations using the McBSP interface of various processors, where CLKX can be used as a reference
clock input for the serial port. When CLKXMODE is low, CLKX on J2 is unconnected.
A pull-down resistor is installed on CLKXMODE, making low the default setting.

OBCLKSEL Routing
OBCLKSEL selects between one of two master clock sources. When OBCLKSEL is high, the onboard
clock is active and used for the master clock. When OBCLKSEL is low, the master clock is taken from
EXTCLK on J2, and the onboard oscillator is disabled.
A pull-down resistor is installed on OBCLKSEL, making connection to an external clock the default setting.

ADS1271 Communication Modes
The ADS1271EVM supports both interface modes for the ADS1271. The interface mode is chosen using
switch S7, located near the top-right corner of the EVM.
Depending of the communication mode, J2 pin 9 (FSR on the bottom connector and FSOUT on the top
connector) connect to different signals (see Table 16).
In SPI mode, FSR is connected to DRDY output signal from the first ADC (U8), while the second ADC
(U7) DRDY line is not connected. FSOUT is not connected.
In FSYNC mode, the FSYNC pins of both ADCs are tied together, and the signal on FSR is copied to the
top connector on pin FSOUT.

These configurations provide th capability of stacking ADS1271EVMs in either mode. To stack EVMs,
each EVM is required to operating in the same mode.
The MMB0 has the ability to determine the configuration of S7 by monitoring the FSDIR pin on J2. This
pin is high when FSOUT is active and FSR is an input, and low when FSOUT is disconnected and FSR is
an output.
5.7
Clock Source
The ADS1271 requires a clock signal for proper operation. Several options are available to source this
clock signal to the ADC.
5.7.1
Onboard Oscillator
A 27MHz clock oscillator is included on the EVM and is selected as the clock source for the device when
OBCLKSEL (J2.19) is high.

External Oscillator
When OBCLKSEL (J2.19) is low, an external clock source should be connected to J2.17. In this setting,
the onboard clock oscillator is shut down.
