16 bit 1MSPS Data Acquisition Reference Design for Single-Ended Multiplexed Applications (TIPD173)

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.

Возможности

Contains Theory, Component Selection, Simulation, Schematic, PCB Layout, and Measured Performance Results Optimized for 900ns (max) 16-bit step-input transient settling time Power: 21.5mW @ AVDD = 3.3V Measured ENOB of 14.58 bits Utilizes ADS8860 (16bit, 1Msps SAR ADC), OPA320 (Input Driver), THS4281 + OPA333 + REF5040 (Reference Driver)
