REF192FSZ-REEL7

Overview

The REF192FSZ-REEL7 is a micropower voltage reference from the Analog Devices REF19x series, providing a nominal output of 2.5 V in an 8-lead SOIC package. It features a maximum temperature coefficient of 5 ppm/°C and an initial accuracy of ±2 mV. The device operates with a supply current of 45 μA and supports a maximum load current of 30 mA. It includes a sleep mode reducing current to 15 μA and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry for high stability
• Incorporates laser trimming of thin-film resistors to achieve precise initial accuracy
• Features low dropout voltage design allowing operation near supply limits
• Includes short-circuit protection and a dedicated sleep mode pin

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 electrical grade (E, F, or G) required for your application, as performance specifications vary by grade. Confirm that the REEL7 suffix indicates tape and reel packaging suitable for automated assembly. Ensure compatibility with the 8-lead SOIC footprint during PCB layout.

Selection Notes

Select this component when a stable 2.5 V reference is needed with minimal power consumption. Consider the E grade for superior temperature coefficients if precision is critical. Verify that the input supply voltage remains within the specified operating range relative to the output voltage.

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, 5.0 V, 3.3 V, and 4.096 V. All variants share similar micropower characteristics and are available in multiple package types such as SOIC, TSSOP, and PDIP.

Replacement Considerations

Other members of the REF19x family, such as REF191, REF193, REF194, REF195, REF196, and REF198, offer different nominal output voltages but share similar package and feature sets. Cross-referencing specific electrical grades is necessary when substituting.
