文档介绍：TI ADS8201低功耗单片数据采集方案
TI 公司的ADS8201是低功耗单片数据采集系统,包括12位采用电容的SAR模数转换器(ADC),高性能连续时间可编增益放大器(PGA)以及全自动扫描8:1复接器,,高达100kSPS吞吐量速率, SCLK 高达25MHz (VD = 5V),主要用在手提通信,传感器接口,手提医疗仪表,, 功能方框图以及精密定位应用电路图和桥式传感器应用电路图.
The ADS8201 is a low-power, complete on-chip data acquisition system optimized for portable applications that require direct connections, wide dynamic range, and automatic operation with very low power consumption. The device includes a 12-bit, capacitor-based, essive approximation register (SAR) analog-to-digital converter (ADC); a high-performance, continuous-time programmable gain amplifier (PGA); and a fully automatic scan, 8-to-1 multiplexer (mux) with breakout to allow for system design flexibility.
Many other features are included to further optimize system operation. Conversion results may be saved in an onboard first-in/first-out (FIFO) buffer and read out at a later time. Each channel has a gain setting that can be loaded automatically when it is selected.
