The AD7730BRZ is a complete analog front end from Analog Devices designed for weigh-scale and pressure measurement applications. It accepts low-level signals directly from a transducer and outputs a serial digital word via a 3-wire SPI interface.
This 24-bit sigma-delta ADC offers a sampling rate of 1.2 kS/s and a signal-to-noise ratio of 123 dB. It features buffered differential inputs, programmable gain front end, and on-chip DAC for offset/tare removal. The device operates with reference voltages from 1 V to 5 V and supports both bipolar and unipolar input polarity.
Key electrical characteristics include a typical power dissipation of 65 mW (125 mW maximum), offset drift of 5 nV/°C, gain drift of 2 ppm/°C, and line frequency rejection greater than 150 dB. The operating temperature range is -40°C to +85°C.
The AD7730BRZ is supplied in a 24-SOIC surface mount package with a 7.50 mm body width. It is available in tape and reel packaging.
The AD7730BRZ has a resolution of 24 bits.
The supply voltage is 5 V.
The operating temperature range is -40°C to +85°C.
The AD7730BRZ comes in a 24-SOIC (0.295", 7.50mm Width) surface mount package.
The manufacturer page states RoHS compliant, but this is unverified and the part contains lead.
The AD7730BRZ uses a 3-wire SPI serial interface.
The AD7730BRZ has 2 analog inputs.
