ADR3650ARMZ

Overview

The ADR3650ARMZ is a precision micropower voltage reference from Analog Devices, delivering a nominal 5.0 V output in an 8-lead MSOP package. It features a maximum temperature coefficient of 6 ppm/°C (A grade) and low initial output voltage error. The device supports high current capacity with typical sourcing of 70 mA and sinking of 20 mA. Operating over a –40°C to +125°C range, it includes shutdown functionality and requires a minimum load capacitance of 0.1 μF for stability.

Feature Summary

• High current output capability allows direct replacement of standard LDO regulators
• Low thermal hysteresis and long-term drift ensure extended system lifetime accuracy
• Integrated shutdown pin reduces quiescent current consumption significantly

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 performance specifications vary between grades. Confirm that the MSOP-8 package matches your PCB footprint. Ensure the input voltage does not exceed the absolute maximum rating of 16 V during operation.

Selection Notes

Select this component when high current drive is needed alongside precision voltage referencing. The A grade offers a 6 ppm/°C temperature coefficient suitable for general precision applications. Verify that the load capacitance meets the minimum requirement of 0.1 μF to maintain stability under all operating conditions.

Part Context

This part belongs to the ADR36xx series of micropower voltage references. It shares architectural similarities with the ADR3625 and ADR3630 but provides a fixed 5.0 V output. The series utilizes proprietary DigiTrim technology for trimming output voltage and temperature coefficients during production.
