ADS1282EVM-PDK Evaluation Module
Description
The ADS1282EVM is a platform for evaluating the
performance of the ADS1282, a high performance,
2-channel, 31-bit, delta-sigma ADC. The ADS1282
board includes the ADS1282 and all the peripheral
analog circuits and components required to extract
optimum performance from the ADC. The evaluation
kit includes the ADS1282EVM board and the
precision host interface (PHI) controller board that
enables the accompanying computer software to
communicate with the ADC over Universal Serial Bus
(USB) for data capture, configuration, and analysis.
