REF1004C-2.5/2K5

Overview

The REF1004C-2.5/2K5 is a two-terminal bandgap reference diode providing a nominal 2.5V output voltage with an initial accuracy of ±20mV at 25°C. It operates within a temperature range of 0°C to +70°C and requires a minimum operating current of 20µA. The device features an average temperature coefficient of 20ppm/°C, low dynamic impedance, and long-term stability of ±20ppm/KHr. Packaged in an 8-lead SOIC (D) format, it supports operation up to 20mA.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix /2K5 indicates tape and reel packaging containing 2500 units per carrier. Confirm the 'C' designation matches the required 0°C to +70°C operating temperature range for your application environment. Ensure compatibility with standard SOIC reflow profiles and moisture sensitivity level ratings before finalizing procurement orders.

Selection Notes

Select this component when a stable 2.5V reference is needed with minimal quiescent current draw. The REF1004C variant is appropriate for commercial temperature ranges, while the REF1004I variant should be chosen if extended industrial temperatures are required. Consider the package type based on assembly requirements, as the /2K5 suffix specifies tape and reel delivery.

Part Context

The REF1004 series serves as a drop-in replacement for the LT1004 and an upgraded alternative to the LM185/385 series references. Manufactured by Texas Instruments under the Burr-Brown lineage, these micropower voltage references offer cost-effective precision without requiring expensive screening of standard devices.
