16 bit 1MSPS Data Acquisition Reference Design for Single-Ended Multiplexed Applications


This TI Precision Verified Design details a systematic design methodology for a 16 bit: 1MSPS: single-ended data acquisition (DAQ) block optimized to achieve excellent settling time: power consumption: static performance and dynamic performance for multiplexed applications.  The design features a 16-bit: high-precision: successive-approximation-register (SAR) analog-digital converter (ADC); low noise: low power and wide bandwidth ADC input drive circuitry; and: a very low drift ADC voltage reference and corresponding reference input drive circuitry.This design is well suited to applications which require low-latency: multi-channel:  data acqusition for multi-sensor measurements such as environmental (temperature: pressure: etc..): biopotential and power measurement.
