AD7730 Datasheet (Analog Devices) - Bridge Transducer ADC

AD7730, Bridge Transducer ADC

The AD7730 is a complete analog front end for weigh-scale and pressure measurement applications.

The device accepts lowlevel signals directly from a transducer and outputs a serial digital word.

The input signal is applied to a proprietary programmable gain front end based around an analog modulator
