Product Summary

The AD7730BRZ 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. The AD7730BRZ is available in a 24-pin plastic DIP, a 24-lead SOIC and 24-lead TSSOP package.
