REF3325AIDCKR

Overview

The REF3325AIDCKR is a series voltage reference from Texas Instruments, housed in an SC-70-3 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.15%. The device exhibits a temperature coefficient of 30 ppm/°C and operates within an input voltage range up to 5.5 V. It draws a typical operating supply current of 3.9 µA and supports a maximum shunt current of 5 mA. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

Provides stable series voltage reference output
Low power consumption suitable for battery applications
Compact SC-70-3 surface-mount packaging

Applications

Portable instrumentation systems
Battery-powered measurement devices
Data acquisition systems requiring precise voltage standards

Procurement Notes

Verify the specific suffix 'CKR' corresponds to the reel packaging configuration as indicated by distributor specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure handling procedures account for moisture sensitivity classification during storage and assembly processes to maintain component integrity.

Selection Notes

Select this component when a 2.5 V reference with low drift and minimal quiescent current is required. The SC-70-3 package offers space efficiency for dense PCB layouts. Consider the 0.15% initial accuracy and 30 ppm/°C temperature stability for precision analog signal conditioning tasks where power budget constraints are critical.

Part Context

This part belongs to the REF3325 family of voltage references manufactured by Texas Instruments. It is categorized under PMIC (Power Management ICs) and specifically serves as a series reference element. The device complements other components in signal chain designs by providing a stable baseline voltage for ADCs, DACs, and sensor interfaces.
