Description

This TI Verified Design is 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 power solution for a full scale input sine wave of 10 KHz. At a total power consumption of less than 35mW: this design has been optimized to achieve an effective resolution greater than 16 bits. The input driver for the ADC uses the OPA320 for low power: low noise and linear rail-to-rail input and output operation. The reference buffer drive utilizes a composite buffer made out of THS4281 & OPA333 to get the desired performance at lowest power consumption.See more TI Precision Designs
