Overview
The ADR3630ARMZ-R7 is a precision micropower voltage reference with a nominal output of 3 V, housed in an 8-lead MSOP package. It features a maximum temperature coefficient of 3 ppm/°C (B grade) and ±0.04% initial accuracy. The device supports up to 16 V input voltage and provides high current capacity, sourcing 70 mA and sinking 20 mA. Quiescent current is 70 µA, dropping to 1.5 µA in shutdown mode. It operates from −40°C to +125°C.
Feature Summary
- High current output capability allows direct replacement for standard low dropout regulators
- DigiTrim technology ensures precise trimming of output voltage and temperature coefficient
- Low thermal hysteresis and long-term drift enhance system lifetime accuracy
- Integrated enable pin facilitates power management with minimal shutdown current
Applications
- Precision power supplies
- Portable instrumentation
- Process transmitters
- Remote sensors
- Medical instrumentation
Procurement Notes
Verify the specific grade (A or B) required for your application, as temperature coefficients and initial accuracy vary between grades. Confirm that the R7 suffix indicates reel packaging compatible with your automated assembly equipment. Ensure the 8-lead MSOP footprint matches your PCB design constraints and thermal requirements.
Selection Notes
Select this component when high drive current is needed alongside precision voltage referencing. The low dropout voltage minimizes power loss compared to traditional LDOs. Consider the thermal resistance and ambient operating conditions to ensure junction temperatures remain within safe limits during high load currents.
Part Context
This part belongs to the ADR3625/ADR3630/ADR3650 family of precision voltage references. These devices utilize proprietary DigiTrim technology for enhanced stability. The family shares similar architectural features but differs in nominal output voltages and specific performance grades, offering flexibility for various precision analog applications.
