ADR3425ARJZ-R2

Overview

The ADR3425ARJZ-R2 is a micropower, high-accuracy CMOS voltage reference with a fixed output of 2.5 V. It features an initial accuracy of ±0.1% and a maximum temperature coefficient of 8 ppm/°C over the industrial range of −40°C to +125°C. The device operates from a supply voltage of 2.7 V to 5.5 V, drawing a maximum quiescent current of 100 μA. It provides an output current capacity of +10 mA sourcing and −3 mA sinking, with a low dropout voltage of 250 mV at 2 mA.

Feature Summary

• Digital trimming via proprietary DigiTrim technology ensures high precision and stability.
• Low output noise maintains signal integrity in critical signal processing systems.
• Integrated enable pin allows for shutdown mode to minimize power consumption.

Applications

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

Procurement Notes

Verify the specific ordering suffix R2 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with the required input voltage range of 2.7 V to 5.5 V for the 2.5 V output variant. Confirm that the SOT-23-6 package dimensions meet the PCB layout requirements.

Selection Notes

Select this component when a stable 2.5 V reference is required with minimal power consumption. The wide operating temperature range supports harsh environments. Consider the low dropout characteristic for applications where the supply voltage is close to the output level. Verify that the load current requirements do not exceed the specified sourcing and sinking limits.

Part Context

This part belongs to the ADR34xx series of micropower voltage references from Analog Devices. The series includes various fixed output voltages optimized for low cost and low power applications.
