ADS8332EVMV2-PDK Evaluation Module
Reed Kaczmarek
This user's guide describes the characteristics, operation, and use of the ADS8332 evaluation module (EVM)
performance demonstration kit (PDK). The ADS8332 is a low-power, 16-bit, 500k samples per-second (SPS)
successive approximation (SAR) analog-to-digital converter (ADC) with an 8-to-1 multiplexer (mux) input. Each
input channel on the device supports unipolar input ranges of 0 V to 4.096 V with single-supply operation. The
EVM-PDK eases the evaluation of ADS8332 device with hardware, software, and computer connectivity through
the universal serial bus (USB) interface. This user's guide includes complete circuit descriptions, schematic
diagrams, and a bill of materials.

Page 4: Overview
1 Overview The ADS8332EVMV2-PDK is a platform for evaluating the performance of the ADS8332 SAR ADC, which is an 8-channel, 16-bit, 4.096-V, multiplexed input ADC device. The evaluation kit includes the ADS8332EVMV2 board and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over USB for data capture and analysis. -

Page 7: Digital Interfaces
There are two devices on the EVM with which the PHI communicates: the ADS8332 ADC (over serial interface) and the EEPROM (over I C). The EEPROM comes preprogrammed with the information required to configure and initialize the ADS8332EVMV2-PDK platform. After the hardware is initialized, the EEPROM is no longer used. 3.1 ADS8332 Digital Interface The ADS8332EVMV2-PDK communicates with the PHI controller through SPI connections. -
Page 8: Power Supplies
When using the ADS8332EVMV2 in conjunction with the PHI controller, the PHI controller supplies the AVDD and DVDD supply. Do not supply external power supply voltages.
