Texas Instruments ADS8881EVMV2-PDK User Manual

This user's guide describes the characteristics, operation, and use of the ADS8881EVMV2 (evaluation
module) paired with a TI Precision Host Interface (PHI) Controller. This board is an evaluation platform for
the ADS8881 and can also be used to evaluate the
differential unipolar successive approximation register (SAR) analog-to-digital converter (ADC) with a
maximum throughput of 1 MSPs. The device is a very-low-power ADC with excellent noise and distortion
performance for AC or DC signals. The REF6045 is a high-precision voltage reference with an integrated
high-bandwidth buffer designed specifically to drive the REF pin of a SAR ADC. On this EVM, the
REF6045 drives the reference of the ADS8881. This user's guide includes complete circuit descriptions,
schematic diagrams, and a bill of materials.
The PHI eases EVM evaluation using additional hardware and software by providing computer
connectivity through the universal serial bus (USB) interface.
