AD7709是一款适合低频测量应用的完整模拟前端,内置一个含PGA的16位Σ-Δ型ADC,可配置为2个全差分输入通道或4个伪差分输入通道。利用AD7709,可以直接转换从20mV至2.56V范围内的输入信号,支持传感器信号直接输入,无需进行信号调节。其它片内功能包括3个软件可配置电流源、可切换基准电压输入、低端电源开关和一个4位数字I/O端口。
The AD7709 is a complete analog front-end for low frequency measurement applications. The AD7709 contains a 16-bit sigma delta ADC with PGA and can be configured as 2 fully-differential input channels or 4 pseudo-differential input channels. Inputs signal ranges from 20mV to 2.56V can be directly converted using the AD7709. These signals can be converted directly from a transducer without the need for signal conditioning. Other on-chip features include three software configurable current sources, switchable reference inputs, low side power switches and a 4-bit digital I/O port.
