REF192GS-REEL

Overview

The REF192GS-REEL is a micropower, low dropout voltage reference from the Analog Devices REF19x series. It provides a fixed nominal output voltage of 2.5 V with an initial accuracy of ±2 mV maximum. The device operates within a supply voltage range of 3 V to 15 V and consumes a maximum supply current of 45 μA. It features a temperature coefficient of 5 ppm/°C maximum over the industrial temperature range of −40°C to +85°C. The component includes short-circuit protection and supports a sleep mode that reduces supply current to less than 15 μA.

• Utilizes patented temperature drift curvature correction circuitry for high stability
• Incorporates laser trimming of thin-film resistors to achieve precise initial accuracy
• Features a dedicated SLEEP pin for power reduction via TTL or CMOS logic levels
• Includes internal short-circuit protection for enhanced reliability

Applications

• Portable instrumentation
• Analog-to-digital (ADC) and digital-to-analog (DAC) converters
• Smart sensors
• Solar powered applications
• Loop-current-powered instruments

Procurement Notes

Verify the specific suffix 'GS' corresponds to the 8-lead SOIC package and REEL packaging format as indicated by the part number structure. Confirm the electrical grade requirements against the datasheet specifications for the target operating temperature range. Ensure compatibility with the required input voltage range and load conditions before finalizing procurement.

Selection Notes

Select this component when a stable 2.5 V reference with micropower consumption is required. The REF192 variant is suitable for applications needing low dropout performance and high initial accuracy. Consider the available packages; while the GS suffix indicates SOIC, other grades may be restricted to specific package types according to the manufacturer's ordering guide.

Part Context

This component belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices Inc. The series is characterized by its ability to operate with very low supply currents and minimal dropout voltage. The REF192 specifically denotes the 2.5 V output version within this family of devices designed for precision measurement systems.

FAQ

How is the sleep mode activated on the REF192GS-REEL?

Sleep mode is enabled by applying a low TTL or CMOS level to the SLEEP pin, which turns off the output and reduces the supply current to less than 15 μA.

What is the purpose of Test Pins 1 and 5?

Test Pins 1 and 5 are reserved for in-package Zener zap trimming during manufacturing. Users should leave these pins unconnected to ensure proper operation.
