The ADS7881EVM is designed for the prototyping and evaluation of the ADS7881 analog-to-digital converter (ADC). This 12-bit, 4MSPS, ADC includes a pseudo-differential input for true bi-polar inputs. The EVM uses a low noise THS4031 inverting gain of one, buffer amplifier. This allows the ADS7881 to operate at optimum performance to meet data sheet specifications. The EVM also contains on board and off board reference voltages that can be selected through jumper settings.
