The AD7781BRZ is a complete, low power front-end solution for bridge sensor products, including weigh scales, strain gages, and pressure sensors. It contains a precision 20-bit sigma-delta ADC with an integrated PGA. The device features a pin-programmable filter response with update rates of 10 Hz or 16.7 Hz. It offers pin-programmable in-amp gain (1 or 128) and an internal clock oscillator. The AD7781BRZ operates from a 2.7V to 5.25V supply and draws only 115 µA typical at gain=1. It includes an internal bridge power-down switch and a status function. The device is specified for the -40°C to +105°C temperature range. It communicates via a 2-wire serial interface that is SPI compatible. The AD7781BRZ is available in a 14-lead narrow body SOIC package (14-SOIC) for surface mount assembly. Typical applications include weigh scales, pressure measurement, industrial process control, and portable instrumentation.
