REF3240AMDBVREP

Overview

The REF3240AMDBVREP is a series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2.098 V to 5.5 V and draws a supply current of 100 µA. It features a low temperature coefficient of 4 ppm/°C and supports a maximum load current of 10 mA. The component is housed in a SOT-23-6 surface-mount package and is rated for operation between -40°C and +125°C.

Feature Summary

• Delivers high precision with a low temperature coefficient of 4 ppm/°C for stable reference performance across temperature variations.
• Offers tight initial accuracy of ±0.2% to ensure reliable voltage referencing in sensitive analog circuits.
• Designed for low power consumption with a supply current of 100 µA, suitable for battery-operated applications.

Applications

• Precision data acquisition systems requiring stable voltage references
• Analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) reference sources
• Instrumentation amplifiers and sensor signal conditioning

Procurement Notes

Verify the specific suffix 'REP' indicates military or enhanced reliability grading as per Texas Instruments documentation. Confirm RoHS compliance status and moisture sensitivity level before integration. Check for obsolescence notices, as this part may be restricted from new designs. Ensure the SOT-23-6 footprint matches the target PCB layout requirements.

Selection Notes

Select this component when a 4.096 V output is required with high thermal stability. The 4 ppm/°C coefficient makes it superior to standard references for wide-temperature applications. Compare against the REF3240AIDBVT if tape-and-reel packaging is preferred over the REP variant's specific handling requirements. Evaluate power budget constraints given the 100 µA quiescent current.

Part Context

This part belongs to the REF32xx-EP family of radiation-tolerant or enhanced product voltage references from Texas Instruments. The 'REP' suffix typically denotes a specific procurement or reliability grade distinct from commercial variants like the REF3240AIDBVR. It shares architectural similarities with other members of the REF32xx series but offers specific performance guarantees documented in the EP datasheet.

Replacement Considerations

Public confirmed substitute: REF3240AIDBVT. Verify functional compatibility regarding output voltage and package pinout before substitution.
