AD7785BRUZ-REEL

Overview

The AD7785BRUZ-REEL is a low power, low noise, complete analog front end for high precision measurement applications. It contains a low noise 20-bit ∑-Δ ADC with three differential analog inputs and an on-chip, low noise instrumentation amplifier. The device features a precision low noise, low drift internal band gap reference and can accept an external differential reference. Other on-chip features include programmable excitation current sources, burnout currents, and a bias voltage generator. The output data rate from the device is software-programmable and can be varied from 4.17 Hz to 470 Hz. The device operates with a power supply from 2.7 V to 5.25 V and consumes a typical current of 400 μA.

Feature Summary

Integrated low noise programmable gain instrumentation amplifier
On-chip precision band gap reference with low temperature drift
Programmable excitation current sources and burnout currents
Simultaneous 50 Hz/60 Hz rejection capability

Applications

Thermocouple measurements
RTD measurements
Industrial process control
Portable instrumentation

Procurement Notes

Verify the exact part number against official Analog Devices documentation before procurement. Confirm that the REEL suffix indicates tape and reel packaging suitable for automated assembly processes. Ensure compatibility with existing system requirements regarding package type and operating temperature range.

Selection Notes

Select this component when a low power, low noise analog front end is required for high precision measurements. Consider the integrated instrumentation amplifier and reference if board space and component count need to be minimized. Evaluate the available update rates and gain settings to ensure they meet the specific signal conditioning needs of the application.

Part Context

The AD7785 is part of Analog Devices' portfolio of precision analog-to-digital converters designed for industrial and portable instrumentation applications. It offers a complete solution by integrating the ADC, amplifier, and reference into a single 16-lead TSSOP package, simplifying the design of high-performance measurement systems.
