DSQC346G电路为该级选择正参考电压或负参考电压。一旦积分器设置为零，ADC电路允许积分器运行，直到其输出达到参考电压。此时，ADC电路选择
去积分操作，并开始计数，直到零交叉电路检测到信号为零。反馈和归零放大器将积分器设置为零，并重复该过程其中输入电压和参考电压的极性相反。
ADC电路在去积分操作期间所取的计数是输入的数字等效值。它发送该信息和极性提供给微处理器。这个微处理器将其放入存储器，并向ADC电路发出信号，开始下一次转换。DSQC346G I/O扩展器总线接口电路FEC模块使用半自定义门阵列进行I/O扩展器总线接口。集成电路（IC）可容纳所有控制逻辑和通信协议。DSQC346G电路提供以下功能：

The DSQC346G circuit selects a positive reference voltage or a negative reference voltage for this stage. Once the integrator is set to zero, the ADC circuit allows the integrator to operate until its output reaches the reference voltage. At this time, ADC circuit selection
De-integrate operation and start counting until the zero crossing circuit detects that the signal is zero. The feedback and zeroing amplifier sets the integrator to zero and repeats the process in which the polarity of the input voltage and the reference voltage is opposite.
The count taken by the ADC circuit during the de-integration operation is the digital equivalent value of the input. It sends this information and polarity to the microprocessor. The microprocessor puts it into the memory and sends a signal to the ADC circuit to start the next conversion.
