The ADS8405EVM is a full-featured evaluation module for the operation of the ADS8405 analog to digital converter. The part is a high-speed SAR (successive approximation register); has 16-bits of resolution, is single channel, and is a parallel interface ADC. The EVM has an on board input signal conditioning circuit. This circuit inverts the incoming signal, applies unity gain, and buffers the signal to the ADS8405 ADC. The EVMs precision reference can be buffered by installing amplifier U1. To reduce loading, digital input/outputs are buffered. Digital decoding is used to allow stacking of multiple EVMs.
