cs5523源码驱动程序，

CS5521/22/23/24/28 是高集成度的ΔΣ模

数转换器（ADC），它通过采用电荷平衡技术达到16-bit（CS5521/23 ）和24-itCS5522/24/28）的性能。本 ADC既可用作2 通道（CS5521/22 ）、也可用4 通道（（CS5523/24 ）和 8 通道（CS5528）

ADC，它内部集成有一个低输入电流、斩波稳定仪表放大器和一个可编程增益放大器（PGA），该PGA提供了25mV 、55mV 、100mV、1V、2.5V，5V 等可选的输入信号范围。为了应用于地基准热电偶，芯片内还集成有一个电荷泵驱动电路，为片上放大器提供负偏置电压。 -the cs5523 source driver CS5521/22/23/24/28 is highly integrated 螖危 analog-to-digital converter (ADC), through the use of charge-balancing technology has reached the 16-bit (CS5521/23) and 24-bit (CS5522/24/28) performance. This ADC can be used either as a 2-channel (CS5521/22), also available 4-channel ((CS5523/24) and 8-channel (CS5528) ADC, the internal integration of a low input current, the chopper-stabilized instrumentation amplifier and a programmable gain amplifier (PGA), the PGA 25mV, 55mV, 100mV, 1V, 2.5V and 5V, and other optional input signal range to be applied to the benchmark thermocouple, the chip also integrates a charge pump drive circuit for the on-chip amplifier to provide a negative bias voltage.
