REF1004C-2.5

Overview

The REF1004C-2.5 is a two-terminal bandgap reference diode manufactured by Texas Instruments, providing a fixed output voltage of 2.5V. It operates within an industrial temperature range of 0°C to +70°C and utilizes an 8-lead SOIC package. The device features an initial accuracy of ±20mV at 100μA reference current and maintains a low average temperature coefficient of 20ppm/°C across the operating range. Minimum operating current is specified at 20μA, with a maximum shunt current capability of 20mA.

Feature Summary

Two-terminal bandgap reference design for high accuracy
Low power consumption suitable for battery applications
Excellent long-term temperature stability
Very low dynamic impedance

Applications

Battery powered test equipment
Portable medical instrumentation
Portable communications devices
A/D and D/A converters
Notebook and palmtop computers

Procurement Notes

Verify that the specific part number matches the required commercial temperature range (0°C to +70°C) rather than the extended industrial variant (-40°C to +85°C). Confirm the package type is the standard 8-lead SOIC. Ensure compliance with RoHS directives if applicable to the project requirements. Check for any specific moisture sensitivity level constraints during assembly.

Selection Notes

Select this component when a cost-effective, micropower voltage reference is needed for portable or battery-operated systems. It serves as a drop-in replacement for the LT1004 and offers improved performance over the LM185/385 series. Choose the 'C' suffix specifically for commercial temperature environments where the wider range of the 'I' suffix is unnecessary.

Part Context

This device belongs to the REF1004 family of micropower voltage references from Texas Instruments. The family includes variants with different output voltages (1.2V and 2.5V) and temperature grades ('C' for commercial and 'I' for industrial). These components are designed to provide stable reference voltages in compact surface-mount packages.
