Product Summary
The AD7730BRZ-REEL is a complete analog front end for weigh-scale and pressure measurement applications. The AD7730BRZ-REEL accepts low-level 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. The applications of the AD7730BRZ-REEL include Weigh Scales and Pressure Measurement.
