AD7787 Datasheet - Analog Devices

AD7787 2-Channel 24-Bit Sigma-Delta ADC

The AD7787 is a low power, complete analog front end for low frequency measurement applications. It contains a low noise 24-bit ∑-∆ ADC with one differential input and one single-ended input that can be buffered or unbuffered. The device operates from an internal clock. Therefore, the user does not .
