Description: 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.

Description: 功放保护，负载输出L,R，都应对地是交流，经R3，R4,C2,C3，入地，交流对地短路，没有直流信号；若有一路含有直流成分，将在电阻电容节点产生或正或负的电压，经二极管桥，整成直流，当电压超过二极管正向电压和Q1导通电压时，Q1导通，Q2，Q3截止，继电器释放，起到某一通道不正常时保护。
此电路还有开机延时保护：开机，电压经R2向C4充电，电压慢慢上升，电压达到D8，Q2，Q3导通电压时，继电器吸合。达到延时接通负载作用-Amplifier protection load output L, R, should all exchanges by R3, R4, C2, C3, into the earth, AC-to-ground short circuit, DC signal if all the way with DC component will be generated in the resistor-capacitor node or a positive or negative voltage, through a diode bridge, the whole into a direct current, when the voltage exceeds a diode forward voltage and Q1 conduction voltage, Q1 turns on, Q2, Q3 is turned off, the relay release play a certain channel is not normal, protection. This circuit also start delay protection: Power voltage by R2 to C4 charge voltage slowly rising voltage reaches D8, Q2, Q3 conduction voltage and relay. Load to reach-delay Platform: |
