AD7708BRU: 16位、8或10通道、低电压、低功耗Σ-Δ ADC
AD7708/AD7718是用于低频测量应用的完整模拟前端器件,内置一个带有可编程增益放大器（PGA）的24位、Σ-Δ ADC,可配置为4/5全差分输入通道或8/10伪差分输入通道,该器件上的两个引脚可配置为模拟输入或基准电压输入。AD7708是AD7718的16位版本。利用这些ADC,可直接转换从20mV到2.56V范围内的输入信号,支持传感器信号直接输入,而无需进行信号调理。
The AD7708/18 are complete analog front-ends for low frequency measurement applications. The AD7718 contains a 24-bit sigma delta ADC with PGA and can be configured as 4/5 fully-differential input channels or 8/10 pseudo-differential input channels. Two pins on the device are configurable as analog inputs or reference inputs. The AD7708 is a 16-bit version of the AD7718. Inputs signal ranges from 20mV to 2.56V can be directly converted using these ADCs. Signals can be converted directly from a transducer without the need for signal conditioning.
