Overview
The AD7792BRUZ-REEL is a low power, low noise analog front end featuring a 16-bit Sigma-Delta ADC with three differential inputs. It integrates a programmable gain instrumentation amplifier (PGA) and an internal bandgap reference. The device operates on a 2.7 V to 5.25 V supply, consuming 400 μA typical current. It supports update rates from 4.17 Hz to 470 Hz and offers up to 23 bits of effective resolution. Key specifications include 40 nV RMS noise at 4.17 Hz with a gain of 64, ±15 ppm INL, and simultaneous 50/60 Hz rejection.
Feature Summary
- Integrates a low noise programmable gain instrumentation amplifier for direct interfacing with small amplitude signals.
- Includes an internal precision bandgap reference with low drift characteristics alongside external reference capability.
- Features on-chip programmable excitation current sources and a bias voltage generator for sensor interface simplification.
Applications
- Thermocouple measurements
- RTD measurements
- Industrial process control
- Portable instrumentation
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and reel configuration. Ensure compatibility with system voltage requirements and communication protocols before integration. Confirm that the component meets all necessary environmental and regulatory standards for the intended deployment environment.
Selection Notes
Select this component for applications requiring high precision with minimal external components. The integrated PGA and reference simplify circuit design compared to discrete solutions. Consider the trade-off between update rate and noise performance when configuring the digital filter settings for optimal system accuracy.
Part Context
This part belongs to the AD7792/AD7793 family of complete analog front ends designed for high precision measurement applications. The AD7792 variant specifically provides 16-bit resolution, distinguishing it from the 24-bit AD7793 while sharing identical peripheral features and pinouts within the 16-lead TSSOP package.
Replacement Considerations
The AD7793 serves as a higher-resolution alternative within the same package and feature set. Verify pinout compatibility and register mapping if substituting with other members of the AD779x series or legacy devices like the AD7792BRU.
