REF192GRU-REEL7

Overview

The REF192GRUZ-REEL7 is a micropower voltage reference from the Analog Devices REF19x series, providing a fixed nominal output of 2.5 V. It operates within an input voltage range of 3 V to 15 V and delivers a maximum load current of 30 mA while consuming only 45 μA of supply current. The device features a temperature coefficient of 25 ppm/°C and low noise performance of 25 μV p-p in the 0.1 Hz to 10 Hz band. It is housed in an 8-TSSOP package and supports operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry for high precision
• Includes a dedicated sleep mode pin to reduce supply current below 15 μA
• Features short-circuit protection and low dropout voltage capability
• Employs laser trimming of thin-film resistors to achieve high initial accuracy

Applications

• Portable instruments
• Analog-to-digital converters (ADCs) and digital-to-analog converters (DACs)
• Smart sensors
• Solar powered applications
• Loop-current-powered instruments

Procurement Notes

Verify the specific suffix RUZ against official documentation to confirm the TSSOP package type and reel packaging configuration. Ensure compatibility with the required electrical grade for your application's accuracy needs. Confirm RoHS compliance status and moisture sensitivity level prior to integration into the manufacturing process.

Selection Notes

Select this component when a stable 2.5 V reference is required with minimal power consumption. The low dropout characteristic allows operation with supply voltages close to the output level. Consider the available electrical grades if tighter initial accuracy or lower temperature coefficients are necessary for the design.

Part Context

This part belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices. The series includes various output voltages such as 2.048 V, 3.0 V, 3.3 V, 4.5 V, 5.0 V, and 4.096 V. All variants share similar micropower architectures and package options including SOIC, PDIP, and TSSOP.

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 zapping during manufacturing. Users should leave these pins unconnected.

How does the device enter sleep mode?

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