REF192ESZ-REEL

Overview

The REF192ESZ-REEL is a micropower voltage reference from the Analog Devices REF19x series, featuring a nominal output of 2.5 V and an initial accuracy of ±0.08%. It operates within a temperature range of -40°C to +85°C with a maximum temperature coefficient of 5 ppm/°C. The device provides a high output current of 30 mA while consuming only 45 μA of supply current. It includes short-circuit protection and low dropout characteristics.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry for high stability
• Features laser trimming of thin-film resistors to achieve precise initial accuracy
• Includes a dedicated sleep mode pin to reduce supply current significantly

Applications

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

Procurement Notes

Verify that the specific suffix 'ESZ' corresponds to the required electrical grade and packaging format. Confirm the reel quantity matches production requirements. Ensure compatibility with the target operating temperature range and input voltage specifications before finalizing procurement.

Selection Notes

Select this component when a stable 2.5 V reference is needed with minimal power consumption. Consider the E-grade performance for applications requiring tight tolerance and low noise. Evaluate the need for the sleep function if power management during idle states is critical for the system design.

Part Context

This part belongs to the REF19x series of precision band gap voltage references. The series offers various fixed output voltages including 2.048 V, 3.0 V, 4.5 V, and 5.0 V. All variants share similar low-power architectures and package options, differing primarily in their nominal output voltage and specific electrical grades.

Replacement Considerations

Other members of the REF19x family such as REF191 or REF193 may serve as alternatives if different output voltages are acceptable. Verify that any substitute maintains the same 8-lead SOIC package and meets the required temperature coefficient and accuracy specifications.
