Analog Devices AD7707 3-Channel 16-Bit Sigma-Delta ADC Datasheet

The AD7707 is a complete analog front end designed for low frequency measurement applications. It functions as a 3-channel device capable of accepting either low level input signals directly from transducers or high level (±10 V) signals, producing a serial digital output via Sigma-Delta conversion technology.

The device features two low level pseudo-differential analog input channels and one high level input channel. It includes an on-chip programmable gain front end with gains ranging from 1 to 128, allowing it to handle various signal ranges without external charge pumps. The modulator output is processed by an on-chip digital filter whose notch frequency can be programmed via a control register.
