Overview
The REF192FS-REEL is a micropower voltage reference from the Analog Devices REF19x series, featuring a nominal output of 2.5 V with an initial accuracy of ±5 mV maximum and a temperature coefficient of 10 ppm/°C maximum over the −40°C to +85°C range. It operates with a supply current of 45 μA maximum and supports up to 30 mA output current. The device utilizes an 8-lead SOIC package and includes short-circuit protection.
Feature Summary
- Micropower operation with low supply current consumption
- Low dropout voltage capability for efficient power usage
- Integrated sleep mode for extended battery life in portable applications
Applications
- Portable instruments
- ADCs and DACs
- Smart sensors
- Solar powered applications
- Loop-current-powered instruments
Procurement Notes
Verify the specific suffix 'F' corresponds to the required electrical grade (±5 mV accuracy) and that the '-REEL' designation matches the tape-and-reel packaging requirement for automated assembly processes. Confirm the manufacturer source directly.
Selection Notes
Select this component when a stable 2.5 V reference is needed with moderate precision requirements. Ensure the operating environment stays within the specified industrial temperature range and that the supply voltage provides sufficient headroom above the output voltage.
Part Context
This part belongs to the REF19x series of precision band gap voltage references. The series employs patented temperature drift curvature correction and laser trimming to achieve high stability. The REF192 variant specifically provides a 2.5 V output level suitable for various analog signal conditioning circuits.

FAQ
What is the function of Test Pins 1 and 5?
Test Pins 1 and 5 are factory test points reserved for in-package Zener zap trimming. They should be left unconnected by the user.
How does the device enter sleep mode?
Sleep mode is enabled by applying a low TTL or CMOS level to the SLEEP pin, which turns off the output and reduces supply current to less than 15 μA.
