REF3240AIDBVT

Overview

The REF3240AIDBVT is a fixed series voltage reference IC manufactured by Texas Instruments, housed in a SOT-23-6 surface-mount package. It provides a stable output of 4.096V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 4.146V to 5.5V and delivers a maximum output current of 10 mA while consuming 135µA of supply current. It features low noise characteristics, specified at 53µVp-p from 0.1Hz to 10Hz and 78µVrms from 10Hz to 1kHz. The unit functions reliably across a temperature range of -40°C to +125°C with a temperature coefficient of 20ppm/°C.

Feature Summary

• Provides a precise fixed output voltage of 4.096V with high initial accuracy.
• Features low-noise performance suitable for sensitive analog signal chains.
• Operates efficiently with low quiescent current consumption.
• Designed for robust operation across extended industrial temperature ranges.

Applications

• Precision data acquisition systems requiring stable reference voltages
• Analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) reference sources
• Portable instrumentation powered by single-supply batteries

Procurement Notes

Verify the specific suffix 'AIDBVT' to confirm the SOT-23-6 package and A-grade accuracy tier. Confirm RoHS3 compliance status as indicated in official documentation. Check for 'Not Recommended for New Design' (NRND) status in current manufacturer catalogs before finalizing procurement plans. Ensure ESD handling protocols are followed during assembly due to the small form factor.

Selection Notes

Select this component when a 4.096V reference is required in a compact SOT-23-6 footprint. Compare noise specifications against application requirements, noting the 53µVp-p low-frequency noise. Evaluate power budget constraints against the 135µA supply current. Consider thermal management needs given the wide operating temperature range up to 125°C.

Part Context

This part belongs to the REF32xx family of precision voltage references from Texas Instruments. It shares architectural similarities with other members like the REF3220 and REF3230 but differs in its fixed 4.096V output setting. The DBVT suffix denotes the specific six-pin SOT-23 package variant optimized for space-constrained printed circuit board layouts.
