CS551数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 Description

The CS5516 and CS5520 are complete solutions for digitizing low level signals from strain gauges, load cells,and pressure transducers. Any family of mV output transducers, including those requiring bridge excitation, can be interfaced directly to the CS5516 or CS5520. The devices offer an on-chip software programmable instrumentation amplifier block, choice of DC or AC bridge excitation, and software selectable reference and signal demodulation.

简介

CS551属于集成电路（IC）的模数转换器（ADC）。由制造生产的CS551模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。
