The AD7730BRZ-REEL7 is a complete analog front end (AFE) for weigh scale and pressure measurement applications. It accepts low-level signals directly from a transducer and outputs a serial digital word. The device integrates a 24-bit sigma-delta ADC with a proprietary programmable gain front end based around an analog modulator.
Key electrical characteristics include a resolution of 230,000 counts peak-to-peak, an offset drift of 5 nV/°C, a gain drift of 2 ppm/°C, and line frequency rejection greater than 150 dB. The device operates from a single +5 V supply and dissipates 125 mW. It supports input voltage ranges from 0 to +80 mV unipolar and ±80 mV bipolar, and accepts reference voltages from 1 V to 5 V.
The AD7730BRZ-REEL7 includes a two-channel programmable gain front end, an on-chip DAC for offset/tare removal, and a programmable digital filter. It communicates via a 3-wire SPI serial interface. The device is housed in a 24-SOIC surface-mount package.
