REF3320AIDCKR

Overview

The REF3320AIDCKR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.048 V with an initial accuracy of 0.15%. It operates within a supply voltage range up to 5.5 V and consumes only 3.9 µA of quiescent current. The device features a low temperature coefficient of 30 ppm/°C and supports a maximum shunt current of 5 mA. Designed for harsh environments, it functions reliably between -40°C and +125°C. This component is housed in a compact SC-70-3 surface-mount package, making it suitable for space-constrained applications requiring stable voltage regulation.

Feature Summary

Ultra-low power consumption of 3.9 µA enables extended battery life in portable devices.
High precision performance with 0.15% initial accuracy and 30 ppm/°C temperature drift ensures signal integrity.
Compact SC-70-3 package facilitates efficient PCB layout in space-sensitive designs.

Applications

Portable instrumentation systems
Battery-powered measurement devices
Data acquisition systems

Procurement Notes

Verify the specific suffix 'CKR' corresponds to the SC-70-3 package and reel packaging configuration. Confirm RoHS compliance status and humidity sensitivity classification prior to integration. Ensure input voltage does not exceed the 5.5 V maximum rating during operation.

Selection Notes

Select this part when a fixed 2.048 V reference is required with minimal power draw. Compare against other REF33xx variants if different output voltages or package types like SOT-23-3 are needed. Verify thermal management requirements for high ambient temperatures up to 125°C.

Part Context

This component belongs to the REF33xx family of nanopower voltage references. The family offers various fixed output voltages and packages including SC-70-3, SOT-23-3, and UQFN-8. All members share similar low-power characteristics and precision specifications tailored for industrial and consumer electronics.
