Overview
The ADR3630ARMZ is a precision, micropower voltage reference with a nominal output of 3.0 V and 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 70 mA sourcing and 20 mA sinking current with a low dropout voltage of 0.15 V at 10 mA. Operating from 3 V to 16 V input, it draws 70 µA quiescent current and includes an enable pin for shutdown mode.
Feature Summary
- High current drive capability allows direct replacement of standard LDO regulators in power supply designs.
- Proprietary DigiTrim technology ensures precise trimming of output voltage and temperature coefficient during production.
- Low thermal hysteresis and long-term drift characteristics enhance system lifetime accuracy.
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 errors differ between them. Confirm that the 8-lead MSOP package footprint matches your PCB layout. Ensure the design accounts for the minimum load capacitance requirement for stability. Check the datasheet for absolute maximum ratings to prevent damage during operation.
Selection Notes
Select this component when high current drive is needed alongside precision voltage referencing. The 3.0 V output suits applications requiring a stable mid-range reference. Consider the low dropout voltage for battery-powered systems where headroom is limited. Evaluate the thermal performance if operating near the upper temperature limits.
Part Context
This part belongs to the ADR3625/ADR3630/ADR3650 family of micropower, high-current voltage references. These devices share similar architectures and features but offer different nominal output voltages. The family utilizes Analog Devices' proprietary DigiTrim technology for enhanced precision and stability across temperature ranges.
Replacement Considerations
The ADR3625 and ADR3650 are functionally similar within the same family but provide 2.5 V and 5.0 V outputs respectively. Verify that the required output voltage matches the 3.0 V specification before substituting.
