ADR3450ARJZ-R2

Overview

The ADR3450ARJZ-R2 is a micropower, high-precision CMOS voltage reference with a fixed 5.0 V output. It features ±0.1% initial accuracy and an 8 ppm/°C maximum temperature coefficient over the −40°C to +125°C range. The device operates from a 5.2 V to 5.5 V input supply, drawing a maximum of 100 μA quiescent current. It provides +10 mA sourcing and −3 mA sinking output current capability with a low dropout voltage of 250 mV at 2 mA. Packaged in a compact 6-lead SOT-23, it utilizes DigiTrim technology for digital trimming.

Feature Summary

Digital trimming via proprietary DigiTrim technology ensures high precision and stability.
Low quiescent current consumption facilitates extended battery life in portable applications.
Integrated enable pin allows for effective power management and system shutdown control.

Applications

Precision data acquisition systems
Industrial instrumentation
Medical devices
Battery-powered devices

Procurement Notes

Verify the specific ordering suffix R2 against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the input voltage requirements align with the 5.2 V to 5.5 V operating range defined in the datasheet. Confirm that the thermal characteristics and package dimensions meet the design constraints for the intended PCB layout.

Selection Notes

Select this component when a stable 5.0 V reference is required within a tight space constraint provided by the SOT-23 package. It is suitable for designs needing low power consumption alongside high accuracy. Consider the narrow input voltage window of 5.2 V to 5.5 V when designing the power supply stage to ensure proper regulation and dropout margins are maintained.

Part Context

This part belongs to the ADR34xx series of micropower voltage references from Analog Devices. The series includes various fixed output voltages such as 1.2 V, 2.048 V, and 3.3 V. All members share similar architectural features, including CMOS construction, low noise profiles, and the use of DigiTrim technology for enhanced performance across industrial temperature ranges.
