Overview
The ADR3420ARJZ-R2 is a micropower, high-precision CMOS voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 8 ppm/°C over the industrial temperature range of −40°C to +125°C. The device operates from an input voltage range of 2.3 V to 5.5 V, drawing a maximum quiescent current of 100 μA. It supports an output current capacity of +10 mA sourcing and −3 mA sinking, featuring low dropout voltage and low output noise.
Feature Summary
- Utilizes proprietary DigiTrim technology for digital trimming of output voltage and temperature coefficient during final assembly to ensure high precision.
- Features a dedicated ENABLE pin that allows for system power management by switching between normal operation and a low-power shutdown mode.
- Incorporates separate Force and Sense pins for both ground and output voltage to facilitate accurate 4-wire Kelvin connections.
Applications
- Precision data acquisition systems
- Industrial instrumentation
- Medical devices
- Battery-powered devices
Procurement Notes
Verify the specific ordering suffix R2 against official documentation to confirm reel packaging specifications. Ensure compatibility with the required input voltage range and load conditions. Confirm RoHS compliance status and check for any regional distribution restrictions or obsolescence notices prior to procurement.
Selection Notes
Select this component when a stable 2.048 V reference is required in space-constrained designs utilizing SOT-23 packages. Consider its low quiescent current for battery-operated applications and its high accuracy for critical signal processing tasks requiring minimal drift over wide temperature variations.
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, 2.5 V, and 3.3 V, all sharing similar architectural features like low power consumption and high precision within the same compact package family.
Replacement Considerations
Consult the manufacturer's selection guide for alternative models within the ADR34xx series or other Analog Devices voltage reference families that match the required output voltage and performance specifications.
