EVM Overview

1 EVM Overview

The ADS8028EVM-PDK is designed to evaluate the ADS8028. The ADS8028 is a 12-bit, 8-channel,

multiplexed, SAR ADC, with a maximum throughput rate of 1 MSPS. The ADS8028 also offers an internal

2.5-V voltage reference and internal temperature sensor with 0.25°C resolution. The ADS8028EVM allows

access to every pin of the converter and makes it easy to connect the ADS8028 SPI™-compatible serial

interface to any host microprocessor or TI DSP based system with 1.8-V, 3.3-V, or 5-V logic capability.

The ADS8028EVM-PDK combines the ADS8028EVM daughtercard with the digital sensor processor

(DSP)-based MMB0 motherboard and ADCPro™ evaluation software for complete evaluation of the

ADS8028.
