REF195GSZ-REEL

Overview

The REF195GSZ-REEL is a precision micropower voltage reference from the Analog Devices REF19x series, housed in an 8-lead SOIC package. It provides a fixed nominal output voltage of 5 V with an initial accuracy of ±0.2%. The device operates within a supply voltage range of 5.1 V to 15 V and draws a maximum supply current of 45 μA under normal conditions. In sleep mode, enabled via the SLEEP pin, the supply current reduces to 15 μA. It features a low dropout voltage, short-circuit protection, and a temperature coefficient of 25 ppm/°C over the industrial temperature range of -40°C to +85°C.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry and laser trimming for high stability.
• Includes a dedicated SLEEP pin to reduce supply current when the output is not required.
• Provides short-circuit protection on the output pin.

Applications

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

Procurement Notes

Verify the specific suffix REEL against the manufacturer's ordering guide to confirm tape and reel packaging specifications. Ensure the electrical grade matches the required initial accuracy and line regulation parameters for the target application environment. Confirm RoHS compliance status as per the latest datasheet revision.

Selection Notes

Select this component when a stable 5 V reference is needed with minimal power consumption. The low dropout characteristic allows operation from supplies close to the output voltage. Consider the extended industrial temperature range if operating conditions exceed standard commercial limits. Verify that the load current requirements do not exceed the 30 mA output capability.

Part Context

This part belongs to the REF19x series of precision band gap voltage references. The series includes various nominal output voltages such as 2.048 V, 2.5 V, 3.0 V, 3.3 V, 4.096 V, and 4.5 V. All variants share similar architectural features including micropower operation and low dropout performance, differing primarily in their trimmed output voltage levels.
