AD7797BRUZ-REEL

Overview

The AD7797BRUZ-REEL is a low-power, 24-bit Sigma-Delta analog-to-digital converter designed for high-precision bridge sensor applications. It features an on-chip instrumentation amplifier with a fixed gain of 128 and a built-in temperature sensor. The device operates within a power supply range of 2.7 V to 5.25 V, consuming a typical current of 250 µA. It supports software-programmable output update rates ranging from 4.17 Hz to 123 Hz. The component utilizes a 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards.

Feature Summary

Integrated instrumentation amplifier with fixed gain of 128 for direct interfacing with small amplitude signals
Built-in temperature sensor for internal bridge compensation
Simultaneous rejection of 50 Hz and 60 Hz line frequencies
Independent digital and analog power supply domains

Applications

Weigh scales
Strain gages
Industrial process control
Portable instrumentation

Procurement Notes

Verify the specific REEL suffix against the manufacturer's ordering guide to confirm tape-and-reel packaging specifications. Ensure compatibility with existing inventory management systems regarding reel dimensions and quantity per package. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, high-resolution ADC with integrated signal conditioning is required. The fixed gain of 128 eliminates the need for external amplifiers in bridge sensor circuits. Consider the 16-lead TSSOP package constraints and verify that the operating temperature range of -40°C to +85°C meets the system requirements.

Part Context

This part belongs to the AD7796/AD7797 family of complete analog front ends. While the AD7796 offers 16-bit resolution, the AD7797 provides 24-bit resolution. Both share identical pinouts and functional blocks, differing primarily in data width and noise performance characteristics defined in the official datasheet specifications.
