TIPD115, Data Acquisition Optimized for Lowest Distortion, Lowest Noise, 18 bit, 1Msps Reference Design

TIPD115, a high performance data acquisition system (DAQ) using an 18-bit SAR ADC, ADS8881 at a throughput of 1MSPS. This design has been optimized to provide the lowest noise/distortion solution for a full scale input sinewave of 10 KHz. This leads to a maximum possible value for Effective Number of Bits (ENOB) at a total power consumption of less than 50mW. The input driver for the ADC uses the fully-differential THS4521 for extremely low distortion, noise and high small signal bandwidth
