The ADC0831 series are 8-bit successive approximation A/D converters with a serial I/O and configurable input multiplexers with up to 8 channels. The serial I/O is configured to comply with the NSC MICROWIRE™ serial data exchange standard for easy interface to the COPS™ family of processors, and can interface with standard shift registers or μPs. The 2-, 4- or 8-channel multiplexers are software configured for single-ended or differential inputs as well as channel assignment.

The differential analog voltage input allows increasing the common-mode rejection and offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution.

ADC0831系列是８位有连续的I/O和可配置的输入的连续的近似I/D变换器有直到8条通道的多路技术。连续的I/O被设置符合NSC MICROWIRE为到的容易的接口的连续的数据交换标准处理器，并且有标准的移动的接口登记的规格或μPs。2-，4-或8通道多路转接器是为单个结束或微分的输入通道赋值一样被设置了的软件。

微分的模拟的电压输入允许增加普通模式拒绝和偏置法模拟零输入电压值。另外,电压引用输入能被调整允许编码任何更小的模拟的电压跨度到决定的完整8位。
