The AD7730LBR is a precision analog front end (AFE) IC from Analog Devices, specifically designed for weigh-scale and pressure measurement applications. It integrates a 24-bit sigma-delta ADC with a programmable gain front end, capable of accepting low-level signals directly from a transducer. The device offers a peak-to-peak resolution of 230,000 counts, ensuring high accuracy in measurement systems. With an offset drift of 5 nV/°C and a gain drift of 2 ppm/°C, the AD7730LBR maintains stability over temperature variations.
The AD7730LBR operates from a single 5 V supply and dissipates 125 mW of power. It features programmable input voltage ranges, including unipolar ranges of 0 mV to +10 mV, +20 mV, +40 mV, and +80 mV, as well as bipolar ranges of ±10 mV, ±20 mV, ±40 mV, and ±80 mV. This flexibility allows the device to interface with various bridge-type sensors. The device also includes a two-channel programmable gain front end and an on-chip DAC for offset/tare removal.
The AD7730LBR is packaged in a 24-SOIC (0.295", 7.50mm Width) surface-mount package. It is RoHS compliant and has a moisture sensitivity level of 1 (unlimited). The device is suitable for use in weigh scales, pressure measurement, and other industrial applications requiring high-resolution analog-to-digital conversion.
