REF3233AIDBVT

Overview

The REF3233AIDBVT is a series voltage reference IC from Texas Instruments, providing 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 100µA. The device features a low temperature coefficient of 4ppm/°C and supports a maximum output current of 10mA. It is housed in a 6-pin SOT-23 package and functions reliably across a temperature range of -40°C to 125°C.

Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Exhibits extremely low temperature drift for stable performance across wide thermal ranges
• Designed for low power consumption suitable for battery-operated systems

Applications

• Precision analog-to-digital converter (ADC) reference inputs
• Data acquisition systems requiring stable voltage sources
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits

Procurement Notes

Verify the specific suffix 'VT' indicates tape-and-reel packaging when sourcing. Confirm the component status as not recommended for new designs if applicable to long-term availability requirements. Ensure compatibility with existing PCB footprints for the SOT-23-6 package during integration planning.

Selection Notes

Select this component when superior temperature stability compared to standard references is required. The 4ppm/°C coefficient makes it suitable for applications where thermal variations impact measurement accuracy. Consider the 10mA output capability against load requirements to ensure adequate drive strength without exceeding specifications.
