REF192GPZ

Overview

The Analog Devices REF192GPZ is a micropower, low dropout voltage reference providing a nominal output of 2.5 V in an 8-lead PDIP package. It features a maximum temperature coefficient of 5 ppm/°C and initial accuracy within ±2 mV. The device operates with a supply current of 45 μA and supports up to 30 mA output current. It includes short-circuit protection and a sleep mode reducing current to 15 μA.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry for high stability
• Offers low dropout voltage operation from supplies as low as 100 mV above output
• Includes a dedicated sleep pin for significant power reduction

Applications

• Portable instruments
• ADCs and DACs
• Smart sensors
• Solar powered applications
• Loop-current-powered instruments

Procurement Notes

Verify the specific suffix 'P' indicates the 8-lead PDIP package configuration when ordering. Confirm that the electrical grade matches the required performance specifications for your application. Ensure compatibility with the extended industrial temperature range requirements.

Selection Notes

Select this component for designs requiring a stable 2.5 V reference with minimal quiescent current consumption. Consider the PDIP package for through-hole assembly needs. Evaluate the need for the sleep function if power management during idle states is critical for the system.

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 precise output voltages and low temperature coefficients across various grades and packages.

Replacement Considerations

Other members of the REF19x family may serve as alternatives depending on package or voltage requirements.
