It can be connected to any Modular EVM System interface card. The ADS1258EVM is available as a stand-alone printed circuit board (PCB) or as part of the ADS1258EVM-PDK, which includes an MMB0 motherboard. As a stand-alone PCB, the ADS1258EVM is useful for prototyping designs and firmware. Note that the ADS1258EVM has no microprocessor and cannot run software. To connect it to a computer, some type of interface is required. 2 Analog Interface For maximum flexibility, the ADS1258EVM 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 ADS1258, as shown in Table 2. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector options. In addition to J1, the J2 header (Samtec part number TSW-108-07-L-D) provides additional analog inputs to accommodate the large number of input channels available on the ADS1258. Most of the pins on J1 and J2 are directly connected, with no filtering or protection. Use appropriate caution when handling these pins. Table 2.

AINCOM is connected to pin 12 on J2. An additional connection is made between J2.11 and J1.10; as a result of this connection, if J2.11 and J2.12 are shorted, and J1.9 and J1.10 are shorted, AINCOM is grounded; if only J2.11 and J2.12 are shorted, AINCOM is available on the EVM analog connector. The multiplexer bypass is available at J2.13–J2.14 (MUXOUP) and J2.15–J2.16 (MUXOUN). Shorting these pairs of pins routes the multiplexer output back to the ADCINN and ADCINP pins through a differential filter. Alternatively, a signal can be applied directly to ADCINN and ADCINP through the filter. Table 3.

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 J6. This header/socket provides access to the digital control and serial data pins of the TSC. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector options. All logic levels on J6 are 3.3V CMOS, except for the I2C pins, which conform to 3.3V I2C rules. The ADS1258 may run at different logic levels, as set using J4. All ADS1258 pins are therefore level-shifted.

J3 is arranged so that GPIO0 and GPIO1 can be used to control START and CS, respectively; see Figure 2 and Figure 5. The PDK firmware controls START through GPIO0. CNTL(J6-1) and FSX(J6-7) are also brought to J3, so they can also be used to control START and CS. Both FSX and CNTL are pulled down, so these pins can be used to keep START and CS low if they are not to be used. 9 7 G1 11 5 G3 CS 3 G5 J6-7 1 12 2 G7 11 1 Figure 2.

The DAC used is a TI DAC8571, controlled through the I2C. The address is set to 1001100. The output of the DAC is multiplied by two, giving a range of approximately 0V to 5V. The DAC circuit is designed for low drift, but is uncalibrated. For absolute accuracy, measure the DAC output and adjust as needed. The DAC high resolution reduces the need for mechanical trimming. Because of the high capacitance load on the buffer amplifier, the DAC step must be limited. The code must not be changed by more than one at a time. (The PDK firmware incorporates a stepper task that limits the slew-rate of the DAC by software.) If the DAC step is too high, the circuit saturates at a certain voltage. To reset the circuit, return the DAC output to 0V. Switches S1 and S2 allow various combinations of the DAC, external supply pins, and the power supply to be selected, as shown in Table 7. Table 7. Reference Selection 6 POSITION S1 REFP S2 REFN Left AVDD AVSS Center DAC GND Right EXTREFP (J1.20) EXTREFN (J1.18) Clock Source The ADS1258 can use either an internal PLL-based clock source or an externally supplied clock. The ADS1258EVM supports either type of clock. For PLL operation, the ADS1258EVM is supplied with a 32.768kHz crystal. This clock mode is selected by pulling GPIO2 on J6 (pin 8) low. In this mode, the generated clock can be measured on TP1, if the proper bit is set in the ADS1258. The clock does not interfere with TOUT. For external operation, a clock signal must be supplied on TOUT on J6 (pin 17), and GPIO2 must be driven high. The level-shifted clock can be measured at TP1. 8 ADS1158EVM, ADS1258EVM, ADS1158EVM-PDK, and ADS1258EVM-PDK Copyright © 2007–2016, Texas Instruments Incorporated SBAU126D – May 2007 – Revised May 2016 Submit Documentation Feedback EVM Operation www.ti.com 7 EVM Operation The following sections provide information on the analog input, digital control, and general operating conditions of the ADS1258EVM. 7.1 Analog Input The analog input sources can be applied directly to J1 (top or bottom side) or through signal-conditioning modules available for the the modular EVM system. Signals can be applied directly to J2 for the additional available channels. 7.2 Digital Control The digital control signals can be applied directly to J6 (top or bottom side). The modular ADS1258EVM can also be connected directly to a DSP or microcontroller interface board, such as the 5-6KInterface or HPA-MCUInterface boards available from Texas Instruments, or the MMB0 if purchased as part of the ADS!258EVM-PDK. For a list of compatible interface and/or accessory boards for the EVM, the ADS1258, or the ADS1158, see the relevant product folder on the TI web site (www.ti.com). 7.3 Power Supply The ADS1258 device can operate in either unipolar or bipolar mode. The ADS1258EVM can therefore function in one of two power-supply configurations, unipolar or bipolar. • In unipolar mode, the ADS1258 device uses a 5V analog supply. No negative power supply is needed in this mode. The PDK requires a +5V dc supply that can be derived from a wall-mount power adapter. • In bipolar mode, the ADS1258 is powered from a ±2.5V dual supply. This configuration requires both a +5V supply and a –5V supply. The power-supply mode is selected using GPIO3 (pin 12) on J6 of the ADS1258EVM. If this pin is low, the mode is bipolar; if high, the mode is unipolar. This pin is pulled high when nothing is connected.

(The ADS1258EVM plug-in is installed as described in the installation section.) 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. 9.1 Using the ADS1258EVM-PDK Plugin The ADS1258EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS1258. It consists of a tabbed interface (see Figure 25), with different functions available on different tabs. These controls are described in this section. You can adjust the ADS1258EVM 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 ADS1258EVM plug-in, the setting is immediately updated on the board. If you unload and reload the plug-in, the software will try to load settings from the board. Settings on the ADS1258EVM correspond to settings described in the ADS1258 data sheet; see the ADS1258 data sheet for details. Because the effective data rate of the ADS1258 depends upon settings of the multiplexer mode, clocks, switch time delay, chopping, and averages, the Effective Data Rate indicator in the upper right corner of the plug-in interface is always visible and updated whenever a setting that effects the data rate is changed. In the upper left corner, the Averages control sets the ADS1258 averaging mode. This may be set to 1, 4, 16, or 64. Note that this is a setting for the ADS1258 device itself; no software averaging is done in the ADS1258EVM-PDK plug-in. 26 ADS1158EVM, ADS1258EVM, ADS1158EVM-PDK, and ADS1258EVM-PDK Copyright © 2007–2016, Texas Instruments Incorporated SBAU126D – May 2007 – Revised May 2016 Submit Documentation Feedback Evaluating with the ADCPro Software www.ti.com 9.1.1 MUX Tab The ADS1258 multiplexer can work in two modes, selected by the controls Fixed Channel or Auto Scan. When set to Fixed Channel mode, the screen will appear as shown in Figure 21. Figure 21. Mux Settings for Fixed Channel Mode On the Fixed Channel tab, the AINP and AINN of the ADS1258 are connected to the pins selected by the radio buttons. In Figure 18, these are both set to AIN0—not a useful setting for measuring an input signal, but quite commonly used for noise testing of the ADS1258. Any channel may be referenced to any other channel; for example, if AINP were set to AIN1, and AINN were set to AIN0, then the signal could be applied between AIN1 and AIN0.

In this mode, the ADS1258 scans through all of the channels selected by checking the box next to the channel name. Note that the AIN channels are single-ended channels, referred to AINCOM. See the ADS1258 data sheet for details on all of the channel configurations. Also notice when changing from Fixed Channel mode to Auto Scan mode, the data rate will be changed to match the limits of the ADS1258. Figure 22.

This setting has effect only when in Auto Scan mode. The delay time can be set on this screen, from no delay (0μs) to 384μs. Figure 23. Switch Delay Settings Through the use of the External Chopping mode, the ADS1258 can remove the offset which might be introduced by signal conditioning circuits. It makes two measurements, which means the sampling rate is half as fast. After the first measurement, the polarity is swapped and the second measurement is made. The ADS1258 averages the two readings, canceling the offset as shown in Figure 24. Multiplexer (chopping) MUXOUTP AINn ADCINP Optional Signal Conditioning ADC AINn MUXOUTN ADCINN Figure 24.

This clock may be selected on this tab, as shown in Figure 26, using the Clock Source controls. Figure 26. Clock Settings The ADS1258 can operate from a 32kHz crystal, and using an internal PLL, generate a 15.729MHz clock. If the Internal setting is selected, this frequency is displayed in the Clock Frequency control. When MMB0 is selected, a 4MHz to 20MHz clock is supplied to the ADS1258EVM. The default frequency is 16MHz, but it can be adjusted in the Clock Frequency control.

Down the center of this screen, the I/O Mode switches set whether each GPIO pin is an input or an output. Figure 27. GPIO Controls When selected as outputs, the Output buttons set the state of the GPIO pins; when pressed and lit, the pin will be driven high; when unlit, the pin will be driven low. If selected as inputs, the LED indicators next on the right hand side of the screen will display the state of the pin (lit for HIGH and unlit for LOW). The state of the GPIO pins is sampled only when the Input button is pressed—in other words, the display will only update when this pin is pressed. 32 ADS1158EVM, ADS1258EVM, ADS1158EVM-PDK, and ADS1258EVM-PDK Copyright © 2007–2016, Texas Instruments Incorporated SBAU126D – May 2007 – Revised May 2016 Submit Documentation Feedback Evaluating with the ADCPro Software www.ti.com 9.1.4 Power and Ref Tab On this tab (shown in Figure 28), the power-supply mode for the ADS1258 may be selected. As explained earlier, the bipolar mode requires both a +5V and a –5V power supply and the appropriate jumper selections on the MMB0, so bipolar mode cannot be selected here if you are using an ac adaptor. With the appropriate power connections, the Power supply can be set to either Unipolar or Bipolar. The ADS1258 Idle mode can be selected to be either Standby (low power, fast startup), or Sleep (lowest power). The VREF Source voltage can either come from an External voltage or you can choose DAC and specify the VREF voltage (up to 5V). When enabled, the Sensor Bias Current Sources (SBCS) can be set for either 1.5μA or 24μA. Figure 28.
