16-Bit: 1MSPS Multiplexed Data Acquisition Reference Design

Description

This design is for a 16-bit 1MSPS single-ended: multiplexed data acquisition system (DAQ) for dc inputs. The system is composed of a 16-bit successive-approximation-register (SAR) analog-to-digital converter (ADC): SAR ADC driver: reference driver: and multiplexer. The design shows the process to optimize a single-ended DAQ to achieve fast settling at a sampling rate of 1MSPS.

Features
  • 1/2 LSB settling in 390 ns Throughput of 1MSPS 4 V output step Measured Effective Resolution of 15.72 bits Measured ENOB of 13.57 bits
Applications
  • Analog input module
