Description

The AD7730BR is a complete analog front end for weigh-scale and pressure measurement applications. The device 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 modulator output is processed by a low pass programmable digital filter,allowing adjustment of filter cutoff, output rate and settling time. AD7730BR Features • Resolution of 230,000 Counts (Peak-to-Peak)• Offset Drift: 5 nV/°C• Gain Drift: 2 ppm/°C• Line Frequency Rejection: >150 dB• Buffered Differential Inputs• Programmable Filter Cutoffs• Specified for Drift Over Time• Operates with Reference Voltages of 1 V to 5 V AD7730BR Applications • Weigh Scales• Pressure Measurement
