The ADS8881EVM-PDK is designed to evaluate the ADS8881 analog-to-digital converter (ADC). The converter is an 18 bit fully differential unipolar Successive-Approximation-Register (SAR) ADC with a maximum throughput of 1MSPS. The EVM includes input and reference drivers enabling the ADC to work within its typical performance specifications. It is designed around a 5V analog supply, which powers an on-board 4.5V reference. A fully differential driver buffers the inputs of the EVM making it possible to also convert bipolar signals. The EVM gives access to every digital pin of the converter making it easy to connect to any host microprocessor or TI DSP based system.
