REF3233AIDBVTG4

Overview

The REF3233AIDBVTG4 is a precision series voltage reference IC manufactured by Texas Instruments, featuring a fixed output of 3.3V with an initial accuracy of ±0.2%. It operates within an input voltage range of 3.35V to 5.5V and draws a supply current of approximately 135µA. The device supports a maximum load current of 10mA and exhibits low noise characteristics, specified at 43µVp-p from 0.1Hz to 10Hz. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides a stable 3.3V reference voltage with high initial accuracy for precision analog circuits.
• Features low power consumption suitable for battery-operated systems.
• Delivers low noise performance to minimize signal interference in sensitive applications.

Applications

• Analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) voltage sources
• Precision measurement instrumentation

Procurement Notes

Verify the specific suffix 'TG4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the SOT-23-6 package type matches your PCB footprint requirements. Check for obsolescence status, as this component may be marked as Not Recommended for New Designs (NRND). Ensure thermal management aligns with the specified operating temperature range during integration.

Selection Notes

Select this component when a fixed 3.3V reference with tight tolerance is required. Compare against other REF32xx variants if different voltage outputs or package sizes are needed. Consider the 10mA output drive capability against your circuit's load requirements. Evaluate the low-noise specification against system sensitivity needs compared to shunt references.

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 REF3233AIDBVR but includes specific packaging and compliance suffixes. The family is designed for general-purpose precision applications requiring stable voltage references in small form factors.
