Product Summary
The AD7730BN is a complete analog front end for weigh-scale and pressure measurement applications. The AD7730BN 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 modulator output is processed by a low pass programmable digital filter, allowing adjustment of filter cutoff, output rate and settling time.
