Voltage Reference
5
www.ti.com
Voltage Reference
The ADS1282EVM has many options for supplying a reference voltage to the ADS1282. Jumper J1 can
select the voltage from the REF5050 (U1) or use ground. The REF5050 supplies 5.0V to the reference for
unipolar mode. If ground is selected, then the voltage reference becomes 2.5V in bipolar mode. This
comes from the voltage difference across the VREFP and VREFN pins on the ADS1282. The voltage is
filtered and buffered by U3 before it is used as a reference for the ADS1282.
The ADS1282 can also be referenced by an external reference voltage using pins J6.18 (REF–) and J6.20
(REF+). Switch S1 chooses either the onboard reference or the external reference voltage that is
connected to the pins of J6. Figure 2 shows switch S1 as it appears on the EVM.
Figure 2. Switch S1
6
Power-Down, Mode and Format Control
The power-down functionality of the ADS1282 is controlled by GPIO4 (J5.14) on the EVM. The
ADS1282EVM-PDK uses the I2C port expander on the EVM to allow the software to control this pin.
7
Clock Source
The ADS1282 clock can come from one of two sources: the onboard 4.096MHz crystal oscillator, or a
clock supplied by a processor on the TOUT pin (J5.17).
7.1
Usage in PDK
If using the ADS1282EVM as part of the ADS1282EVM-PDK, the J3 jumper should be set to the DVDD
position. Using the onboard 4.096MHz crystal oscillator allows the the ADS1282EVM-PDK software to
recognize the EVM using the software provided.
7.2
Usage as a Stand-Alone EVM
If using the EVM in your own system and not with the PDK hardware and software, the J3 jumper can be
used to select the clock. The jumper can be used to always select the 4.096MHz crystal (DVDD position)
or allow the onboard clock to be controlled by GPIO5 (J5.19), as shown in Figure 3. The P05 (U7.6) pin
allows the I2C interface to program a clock to GPIO5.

EVM Operation
This section provides information on the analog input, digital control, and general operating conditions of
the ADS1282EVM.
8.1
Analog Input
The two differential input sources can be applied directly to J6 (top or bottom side) or through signalconditioning modules available for the modular EVM system. Each input is connected directly through an
OPA1632 buffer before reaching the ADS1282. The Common-Mode Voltage (VCOM) for the input buffer
operational amplifiers is 2.5V supplied from the REF5025.
8.2
Digital Control
The digital control signals can be applied directly to J5 (top or bottom side). The modular ADS1282EVM
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, or the MMB0 if purchased as part
of the ADS1282EVM-PDK. For a list of compatible interface and/or accessory boards for the EVM or the
ADS1282, see the relevant product folder on the TI web site. Some of the digital signals are controlled
directly with pins on J5. Other signals, such as SYNC, MFLAG, PMODE, and RESET controls, can only
be controlled by U7. These signals are configured and read using the I2C signals on pins 16 and 20 of J5.
The Format and Mode pins can be controlled by both methods (GPIO pins on J5, and the I2C control from
U7).
8.3
Default Jumper Settings and Switch Positions
Figure 4 shows the jumpers found on the EVM and the respective factory default conditions for each.
Figure 4. ADS1282EVM Default Jumper Locations
There is only one switch, S1, located on the ADS1282EVM; it is used to set the reference voltage (VREF).
The default position is to the left, indicating that the EVM is to use the onboard reference voltage.

Evaluating Performance with the ADCPro Software
The evaluation software is based on ADCPro, a program that operates using a variety of plug-ins. (The
ADS1282EVM plug-in is installed as described in the installation section, Section 10.)
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 kind of plug-in can be loaded at a time. If you select a different plug-in, the previous
plug-in is unloaded.
11.1 Using the ADS1282EVM-PDK Plug-in
The ADS1282EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS1282. It
consists of a tabbed interface (see Figure 15), with different functions available on different tabs. These
controls are described in this section.
You can adjust the ADS1282EVM 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 ADS1282EVM plug-in, the setting immediately updates on the board.
Settings on the ADS1282EVM correspond to settings described in the ADS1282 product data sheet; see
the ADS1282 data sheet (available for download at the TI web site) for details.
11.1.1
Controls Tab
ADCPro can receive data from the ADS1282 at five different data rates. The data rate is controlled by the
DR[2:0] Register control (shown in Figure 22). The data rate choices are determined by the digital filter
that is used. The setting of the register selects the data rate and displays it to the right of the screen.
Figure 22. Data Rate Select
The PGA found on the ADS1282 can be set through ADCPro. The Gain control is used to set binary gains
by setting the register bits accordingly (as shown in Figure 23).
Figure 23. PGA Gain Select
ADCPro can access to the Chop control. Chop will take two readings, a normal reading and one with the
input pins switched. It then averages the two readings for a final output result. Doing this averaging
removes the offset, offset drift, and reduces the noise reading. See the ADS1282 product data sheet for
more information on Chop.
The Operating Mode control allows optimization of noise and power. Either Low Power or High
Resolution can be selected.
NOTE: Low-power mode is no longer supported

The Mux control determines which input channel is sent through the converter. The five options, shown in
Figure 24, are explained in the product data sheet.
Figure 24. Mux Select
When switch S1 is switched to external VREF, VREFP and VREFN control the bounds for the reference
voltage.
The Standby and Wakeup controls send the corresponding commands to the ADS1282 (as illustrated in
Figure 25). Data cannot be collected while the device is in Standby mode.

11.1.2
Filter Tab
There are three different digital filter options in ADCPro. A Sinc Filter + LPF Filter Block is the default filter.
The Low-Pass Filter (LPF) can be removed or a High-Pass Filter (HPF) can be added (as shown in
Figure 26).
Figure 26. Digital Filter
The LPF Phase Response control can be set to either Linear phase or Maximum phase. The Digital
Filter, LPF Phase Response and the High-pass Filter Corner Frequency are controlled in the Filter
Tab (as Figure 27 shows).
Figure 27. Filter Tab
11.1.3
Calibration Tab
A calibration feature is integrated into the ADS1282 to correct for offset and gain errors. The
ADS1282EVM-PDK software is designed to allow the user to use either the built-in system calibration
commands or manually calibrate the device by directly entering the values for the offset and gain registers
of the ADS1282.

11.1.3.1
www.ti.com
System Calibration
The Start Calibration button is used for system calibration by sending the Offset and Gain Calibration
commands to the ADS1282. Which command is sent is determined by the radio buttons in the Calibration
Type groupbox (see Figure 28). The calibrations should be performed separately before testing. See the
ADS1282 product data sheet for more information on calibration.
A zero input signal must be applied before performing offset calibration. The Offset radio button should be
selected. When Start Calibration is pushed, the offset calibration is performed and the resulting value is
reflected in the OFC register display (in hex).
A full-scale dc input should be applied for gain calibration. The Gain radio button should be selected.
When Start Calibration is pushed, the gain calibration is performed and the resulting value is reflected in
the FSC register display (in hex).
11.1.3.2
Manual Calibration
The values of the offset (OFC) and full-scale (FSC) calibration registers can be directly written to if there
are different offset and gain values desired to be used. The OFC or FSC registers are written to the
ADS1282 when the value in these controls changes and the user deselects the text box. For ease of
entry, the gain or offset values are entered only in the OFC or FSC controls; the actual values placed in
each of the three corresponding registers on the ADS1282 are displayed on this tab.

Collecting Data
Once you have configured the ADS1282 for your test scenario, press the ADCPro Acquire button to start
the collection of the number of datapoints specified in the Test plug-in Block Size control. The
ADS1282EVM-PDK plug-in disables all the front panel controls while acquiring, and displays a progress
bar as shown in Figure 29.

For more information on testing analog-to-digital converters in general and using ADCPro and Test plugins, refer to the ADCPro User Guide.
11.2 Troubleshooting
If ADCPro stops responding while the ADS1282EVM-PDK is connected, try unplugging the power supply
from the PDK. Unload and reload the plug-in before reapplying power to the PDK.
