REF102CU

Overview

The REF102CU is a precision 10V voltage reference from Texas Instruments, housed in an 8-SOIC package. It features a maximum drift of 2.5ppm/°C across the industrial temperature range, achieved via laser trimming without requiring a heater. The device operates on a single supply between 4.75V and 36V, drawing 5.5mA typical current. It delivers a fixed 10V output with ±0.025% initial accuracy and supports up to 10mA load current.

Feature Summary

• Laser-trimmed for high precision without thermal regulation
• Low power consumption suitable for space-constrained designs
• Fast warm-up time enabling rapid system initialization

Applications

• Industrial sensor signal conditioning
• Data acquisition systems
• Precision measurement instrumentation

Procurement Notes

Verify the suffix 'CU' confirms the commercial temperature grade and SOIC-8 packaging. Confirm that the specific revision matches your design requirements, as older stock may vary. Ensure compatibility with your PCB footprint and soldering profile. Check for moisture sensitivity levels if storage conditions are uncontrolled.

Selection Notes

Select this component when a stable 10V reference is required with minimal self-heating effects. The low drift specification suits applications demanding long-term stability. Consider the 10mA output capability against your load requirements. Evaluate the SOIC-8 package size against available board space constraints.

Part Context

Part of the REF102 series offering precision voltage references. Designed for applications needing high accuracy without complex thermal management. Provides a reliable baseline for analog circuits where noise and drift must be minimized. Complements other TI amplifier and ADC families.

Replacement Considerations
