Overview
The ADR3440ARJZ-R2 is a micropower, high-accuracy CMOS voltage reference providing a fixed output of 4.096 V. It features ±0.1% initial accuracy and a maximum temperature coefficient of 8 ppm/°C over the industrial range of −40°C to +125°C. The device operates with an input voltage between 4.3 V and 5.5 V, drawing a maximum quiescent current of 100 μA. It supports +10 mA sourcing and −3 mA sinking output currents with a low dropout voltage of 250 mV at 2 mA. Packaged in a 6-lead SOT-23, it utilizes DigiTrim technology for precision trimming.
Feature Summary
- Digital trimming via proprietary DigiTrim technology ensures high accuracy and stability.
- Low output noise helps maintain signal integrity in critical signal processing systems.
- Integrated enable pin allows for effective power management and shutdown control.
Applications
- Precision data acquisition systems
- Industrial instrumentation
- Medical devices
- Battery-powered devices
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm that the input supply voltage meets the minimum operating requirement of 4.3 V for proper regulation. Ensure thermal constraints are addressed within the 6-lead SOT-23 package limits during system design.
Selection Notes
Select this component when a stable 4.096 V reference is required in space-constrained designs. The low quiescent current makes it suitable for battery-operated applications. Verify that the load requirements do not exceed the specified sourcing and sinking current capabilities.
Part Context
This part belongs to the ADR34xx series of micropower voltage references from Analog Devices. The family includes various fixed output voltages optimized for low cost and low power consumption while maintaining high precision across the industrial temperature range.
Replacement Considerations
Other members of the ADR34xx family offer different fixed output voltages but share similar electrical characteristics and pinouts. Verify compatibility if substituting with other variants in the same series.
