Overview
The REF192ESZ-REEL7 is a micropower voltage reference from the Analog Devices REF19x series, providing a fixed nominal output of 2.5 V in an 8-lead SOIC package. It features a maximum temperature coefficient of 5 ppm/°C and an initial accuracy of ±0.08%. The device operates with a supply current of 45 μA and supports a maximum load current of 30 mA. It functions within an extended industrial temperature range of −40°C to +85°C.
Feature Summary
- Utilizes patented temperature drift curvature correction circuitry for high stability
- Includes short-circuit protection for output safety
- Features a dedicated sleep mode pin for reduced power consumption
Applications
- Portable instrumentation
- Analog-to-digital converters (ADCs)
- Digital-to-analog converters (DACs)
- Smart sensors
- Loop-current-powered instruments
Procurement Notes
Verify the specific suffix 'ESZ' corresponds to the E-grade electrical specifications and the SOIC-8 package type. Confirm that the REEL7 designation matches the required tape and reel packaging format for automated assembly processes before finalizing procurement orders.
Selection Notes
Select this component when a stable 2.5 V reference is required with low quiescent current consumption. The E-grade specification ensures tighter tolerance limits compared to lower grades. Ensure the application environment remains within the specified −40°C to +85°C operating temperature range for guaranteed performance.
Part Context
This part belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices. The series utilizes laser trimming of thin-film resistors to achieve low temperature coefficients. The REF192 variant specifically provides a 2.5 V output, distinguishing it from other members like the REF191 or REF193 which offer different nominal voltages.

FAQ
What is the function of Pin 1 and Pin 5?
Pin 1 and Pin 5 are factory test points reserved for in-package Zener zapping during manufacturing. They must remain unconnected by the user.
How does the sleep mode operate?
Applying a low TTL or CMOS level to the SLEEP pin turns off the output and reduces the supply current to less than 15 μA.
