Overview
The ADR3420ARJZ-R7 is a micropower, high-precision CMOS voltage reference providing a nominal output of 2.048 V. It features an initial accuracy of ±0.1% and a maximum temperature coefficient of 8 ppm/°C over the −40°C to +125°C range. The device operates with a supply voltage between 2.3 V and 5.5 V, drawing a maximum quiescent current of 100 μA. It supports a sourcing output current of 10 mA and sinking current of 3 mA.
Feature Summary
- Utilizes proprietary DigiTrim technology for digital trimming of output voltage and temperature coefficient during final assembly.
- Features separate Force and Sense pins for GND and VOUT to enable four-wire Kelvin connections for improved measurement accuracy.
- Includes an Enable pin that allows the device to enter a low-power shutdown mode with reduced current consumption.
Applications
- Precision data acquisition systems
- Industrial instrumentation
- Medical devices
- Battery-powered devices
Procurement Notes
Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with the required input voltage range and load conditions before integration. Confirm RoHS compliance status through the manufacturer's product compliance portal or datasheet revision history.
Selection Notes
Select this component when a stable 2.048 V reference is required in space-constrained designs utilizing SOT-23 packages. Consider the 8 ppm/°C temperature coefficient and ±0.1% initial accuracy for applications demanding high precision. Evaluate the 100 μA quiescent current against battery life requirements for portable equipment.
Part Context
This part belongs to the ADR34xx family of micropower voltage references from Analog Devices. The family includes variants with different fixed output voltages, such as 1.2 V, 2.5 V, and 3.3 V, all sharing similar performance characteristics and packaging options designed for low-cost, low-power applications.
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 accuracy specifications.
