AD7783 Datasheet Pin Configured 24-Bit ADC

Manufacturer: Analog Devices

General Description

ANALOG INPUT CURRENT SOURCES REFERENCE INPUT AIN(+) AIN(–) IOUT1 IOUT2 AD7783 CS DOUT/RDY SCLK XTAL1 REFIN(+) REFIN(–) GND XTAL2 32.768kHz CRYSTAL DIGITAL INTERFACE The AD7783 is a complete analog front end for low-frequency measurement applications.

The 24-bit sigma-delta ADC contains one fully differential input channel that can be configured with a gain of 1 or 16 allowing full-scale input signal ranges of ± 2.56 V or ± 160 mV from a +2.5 V differential reference input.

It also contains two 200 µA integrated current sources.
