REF2025AIDDCR

Overview

The REF2025AIDDCR is a dual-output series voltage reference IC manufactured by Texas Instruments, housed in a SOT-23-THIN (TSOT-23-5) package. It provides fixed output voltages of 1.24V and 2.5V with an initial accuracy tolerance of ±0.05%. The device operates within an input voltage range of 2.52V to 5.5V and delivers a maximum output current of 20 mA while consuming only 460µA of supply current. It features a low temperature coefficient of 8ppm/°C and low noise performance of 12ppm p-p from 0.1Hz to 10Hz. The component supports surface mount installation and functions reliably across a wide operating temperature range of -40°C to 125°C.

Feature Summary

• Dual-output architecture providing simultaneous 1.24V and 2.5V references in a compact footprint
• High precision stability with ±0.05% initial accuracy and low 8ppm/°C temperature drift
• Ultra-low power consumption design suitable for battery-operated applications

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage rails
• Portable instrumentation powered by single-cell batteries

Procurement Notes

Verify the specific suffix DDCC or DDCR against the manufacturer's latest datasheet to confirm pinout compatibility and marking codes. Ensure the procurement channel provides original packaging documentation to validate authenticity. Check for RoHS3 compliance status if environmental regulations apply to your assembly process. Confirm that the SOT-23-THIN package dimensions match your PCB land pattern requirements before finalizing orders.

Selection Notes

Select this component when dual independent voltage outputs are required from a single package to save board space. It is appropriate for designs needing high accuracy without the complexity of adjustable references. Consider the 20mA output capability for driving moderate loads directly. Evaluate the 460µA quiescent current against system power budgets for portable devices. Compare the 8ppm/°C drift against thermal environment constraints to ensure long-term stability meets specification.

Part Context

This part belongs to the REF2025 family of dual-output, low-drift, low-power voltage references from Texas Instruments. The family shares similar architectural characteristics but varies in output voltage combinations and package options. It serves as a compact alternative to discrete resistor divider networks or single-output references in space-constrained designs.
