REF195ES-REEL

Overview

The REF195ES-REEL is a precision micropower, low dropout voltage reference from the Analog Devices REF19x series. It provides a fixed nominal output voltage of 5 V with an initial accuracy of ±0.04%. The device operates within a supply voltage range of 5.1 V to 15 V and delivers a maximum output current of 30 mA. Key electrical specifications include a maximum temperature coefficient of 5 ppm/°C, a maximum supply current of 45 μA, and a sleep mode current of 15 μA. It features short-circuit protection and is housed in an 8-lead SOIC package.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry and laser trimming for high stability.
• Includes a dedicated SLEEP pin that reduces supply current when activated by TTL or CMOS logic levels.
• Provides integrated short-circuit protection to safeguard the device under fault conditions.

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 'ES' against the manufacturer's ordering guide to confirm the exact grade and packaging configuration. Confirm the component status as active or obsolete via official documentation before procurement planning. Ensure the reel quantity matches project requirements.

Selection Notes

Select this component for designs requiring a stable 5 V reference with minimal quiescent current consumption. The low dropout characteristic allows operation with supply voltages close to the output level. Verify that the required accuracy grade meets the system tolerance needs.

Part Context

This part belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices. The series offers various fixed output voltages and packages, including SOIC, TSSOP, and PDIP. The REF195 variant specifically targets applications needing a precise 5 V rail.

Replacement Considerations

Consult the REF19x Series Ordering Guide for direct substitutes with different output voltages or package types. Cross-reference with other Analog Devices voltage reference families if specific performance parameters differ.
