REF4132B40DBVR

Overview

The REF4132B40DBVR is a precision series voltage reference manufactured by Texas Instruments, designed for automotive and industrial applications. It delivers a fixed output voltage of 4.096 V with an initial accuracy of ±0.05%. The device features a low temperature coefficient of 30 ppm/°C and operates within an input voltage range of 3.05 V to 5.5 V. It supports a maximum shunt current of 10 mA and functions reliably across a temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount case, it ensures stable performance in space-constrained designs.

Feature Summary

• Provides high-precision fixed output voltage with tight initial accuracy tolerance
• Engineered for automotive environments with extended wide operating temperature range
• Utilizes small-footprint surface-mount packaging for efficient board space utilization

Applications

• Automotive sensor signal conditioning circuits
• Precision analog-to-digital converter (ADC) reference inputs
• Data acquisition systems requiring stable voltage baselines

Procurement Notes

Verify the specific suffix codes against the official Texas Instruments datasheet to confirm exact electrical tolerances and package variations. Ensure compatibility with AEC-Q100 automotive qualification requirements if deploying in vehicle systems. Cross-reference pinout configurations to prevent integration errors during PCB layout and assembly processes.

Selection Notes

Select this component when a stable 4.096 V reference is required in automotive or industrial settings. The ±0.05% accuracy suits high-precision measurement tasks. Consider the SOT-23-5 package size for space-limited layouts. Evaluate thermal management needs given the 125°C maximum junction temperature rating and low power consumption characteristics.

Part Context

This part belongs to the REF4132 family of low-drift, low-power series voltage references. The 'B' indicates the ±0.05% accuracy grade, while '40' specifies the 4.096 V output voltage. The 'DBVR' suffix denotes the SOT-23-5 package type with tape-and-reel shipping. It serves as a robust alternative to general-purpose references in demanding electronic applications.

Replacement Considerations

The LM4132BMFX-4.1/NOPB is a documented substitute offering similar 4.096 V output and SOT-23-5 packaging. Verify that the replacement meets the required ±0.05% accuracy and 30 ppm/°C drift specifications. Confirm pinout compatibility and thermal performance before finalizing any design substitution.
