This user's guide describes the characteristics, operation, and use of the ADS1x7xEVM-PDK. These
evaluation module kits (EVM-PDK) are an evaluation system for the ADS1278, a 24-bit, 8 channel, delta-
sigma analog-to-digital converter (ADC), the ADS1178, a 16-bit version of the ADS1278 and the
and ADS1174, which are 4 channel versions of the ADS1278 and ADS1178, respectively. The EVM-PDK
allows evaluation of all aspects of the ADS1x7x devices.
This document includes an EVM QuickStart, hardware and software details, bill of materials, and
schematic.

For use in the ADS1x7xEVM-PDK, the state of these pins is controlled by software, using the I C port expanders (U7 and U8) on the EVM. When using the EVM with the EVM-PDK, the DIP switches S1 and S2 must all be switched down (toward the center of the board). -

In TDM mode, the data from all eight channels can be observed on the DOUT1 pin of the converter. The DOUT1 signal is used by the ADS1x7xEVM-PDK to read back and display all the channels. The digital data output pin on the digital interface header J4 is connected to DOUT1 signal via a D flip-flop. The D flip-flop provides a half cycle delay in order to align the data correctly to reach the higher speeds of the device. - Page 16 Resistor, Chip, 1/10W, 5% Rohm MCR03EZPJ473 Switch, SMD Low Profile 08 Position 218-8LPST These parts are not installed for ADS1274 and ADS1174 ADS1x7xEVM-PDK SBAU197A – February 2012 – Revised January 2016 Submit Documentation Feedback Copyright © 2012–2016, Texas Instruments Incorporated...
