TI ADS1248 24位精密ADC传感器应用评估方案

TI 公司的ADS1246, ADS1247和ADS1248是高度集成的24位精密ADC,集成了低噪音可编程增益放大器(PGA),带单周期设定数字滤波器的精密Delta-Sigma ADC以及振荡器,组成了完整的温度/桥式传感器应用包括热耦合,电热调节器,RTD和应力测量的前端解决方案.本文介绍了ADS1246, ADS1247和ADS1248主要特性,以及ADS1248EVM评估板的主要特性,详细电路图和材料清单(BOM).

The ADS1246, ADS1247, and ADS1248 are highly-integrated, precision, 24-bit analog-to-digital converters (ADCs). The ADS1246/7/8 feature an onboard, low-noise, programmable gain amplifier (PGA), a precision delta-sigma ADC with a single-cycle settling digital filter, and an internal oscillator. The ADS1247 and ADS1248 also provide a built-in, very low drift voltage reference with 10mA output capacity, and two matched programmable current digital-to-analog converters (DACs). The ADS1246/7/8 provide a complete front-end solution for temperature/bridge sensor applications including thermal couples, thermistors, RTDs, and strain-gauge applications.
