TIPD112, Data Acquisition for MUX and Step Inputs, 18 bits, 1uS Full Scale Response

TIPD112, 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 18-bit settling performance for a Full Scale Step Input signal, thus leading to excellent system linearity. Such an input stimulus is more applicable in multiplexed applications for transition between channels with different input voltages. The input driver for the ADC uses the OPA350 for high bandwidth (small/large signal), output current drive and linear rail-to-rail input and output operation
