REF192ES

Overview

The REF192ES is a micropower, low dropout voltage reference from the Analog Devices REF19x series. It provides a nominal output voltage of 2.5 V with an initial accuracy of ±0.08%. The device features a maximum temperature coefficient of 5 ppm/°C and a maximum supply current of 45 μA. It supports a maximum load current of 30 mA and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Micropower operation with low supply current consumption
• Low dropout voltage capability for minimal headroom requirements
• Integrated sleep mode for further power reduction
• Short-circuit protection for output overload safety

Applications

• Portable instrumentation
• Analog-to-digital converters (ADCs)
• Digital-to-analog converters (DACs)
• Smart sensors
• Loop-current-powered instruments

Procurement Notes

Verify the specific suffix 'ES' against official documentation to confirm package type and grade. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering information matches the exact electrical grade specifications needed for your circuit design.

Selection Notes

Select this component when a stable 2.5 V reference is required in space-constrained designs. Consider its low quiescent current for battery-operated applications. Evaluate the low dropout characteristic if the supply voltage margin is limited. Verify compatibility with ADC or DAC input requirements.

Part Context

The REF192ES belongs to the REF19x series of precision band gap voltage references. This family utilizes patented temperature drift curvature correction and laser trimming for high stability. The series includes various fixed output voltages and is available in multiple packages including SOIC and TSSOP.

Replacement Considerations

Direct replacement options include other members of the REF19x series such as the REF192GPZ or REF192ESZ, provided they match the required package and electrical grade specifications.
