REF2033AIDDCT

Overview

The REF2033AIDDCT is a dual-output voltage reference from Texas Instruments, housed in a SOT-23-Thin-5 package. It provides fixed output voltages of 1.65 V and 3.3 V with an initial accuracy of ±0.05%. The device features a low temperature coefficient of 8 PPM/°C and supports a maximum input voltage of 5.5 V. It operates within a junction current range up to 20 mA and functions across a temperature range of -40°C to +125°C.

Feature Summary

Dual-output architecture delivering both VREF and VREF/2 simultaneously
Low-drift performance characterized by an 8 PPM/°C temperature coefficient
High precision with an initial accuracy tolerance of ±0.05%
Compact surface-mount design suitable for space-constrained applications

Applications

Interleaved analog-to-digital converter (ADC) systems
Portable instrumentation requiring stable reference sources
Battery-powered measurement devices
Data acquisition systems

Procurement Notes

Verify the specific suffix 'DCT' corresponds to the SOT-23-Thin-5 package and tape-and-reel packaging configuration. Confirm that the A-grade accuracy rating meets the system requirements for initial voltage tolerance. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits to maintain the documented drift characteristics.

Selection Notes

Select this component when a single IC must provide two distinct reference levels without external resistor dividers. The low power consumption and small footprint make it suitable for portable designs. Compare against series references if higher output currents are required, as this shunt-type device has specific current handling limitations.

Part Context

This part belongs to the REF20xx family of low-drift, low-power voltage references. It is designed to replace older generation references while offering improved accuracy and smaller physical dimensions. The dual-output capability simplifies circuit design by eliminating the need for external scaling networks.
