REF4132B30DBVR

Overview

The REF4132B30DBVR is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 3V with an initial accuracy of ±0.05% and a temperature coefficient of 30ppm/°C. The device operates within an input voltage range of 3.05V to 5.5V and draws a supply current of 100µA. It features low noise characteristics, specified as 15µVp-p in the 0.1Hz to 10Hz band and 24µVrms from 10Hz to 10kHz. The component supports a maximum output current of 10mA and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial tolerance
• Maintains stable performance over wide operating temperature ranges
• Provides low-noise signal generation suitable for sensitive analog circuits

Applications

• Precision data acquisition systems requiring stable reference voltages
• High-resolution analog-to-digital converter (ADC) biasing
• Medical instrumentation and diagnostic equipment
• Industrial process control sensors

Procurement Notes

Verify the specific suffix DBVR indicates the SOT-23-5 surface-mount package configuration. Confirm that the B-grade designation corresponds to the ±0.05% initial accuracy specification. Ensure compatibility with the required 3V output level and 100µA supply current constraints for the target design.

Selection Notes

Select this component when a fixed 3V reference with ±0.05% accuracy is required. It is suitable for applications needing low noise and operation up to 125°C. Consider the SOT-23-5 footprint for space-constrained designs. Verify input voltage stays within the 3.05V to 5.5V range to ensure proper regulation.

Part Context

This part belongs to the REF4132 family of precision series voltage references from Texas Instruments. The family offers various output voltages and accuracy grades. The REF4132 series is designed for applications demanding high stability and low power consumption in compact packages.

Replacement Considerations

LM4132AMFX-3.0/NOPB: Series reference, 3V output, SOT-23-5 package, but higher temperature coefficient (30ppm/°C vs 30ppm/°C similar, check specific grade). REF4132A50DBVRQ1: Automotive qualified, 5V output, different voltage.
