Overview
The ADR3650ARMZ-R7 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 for the A grade and ±0.08% initial accuracy. The device supports up to 70 mA sourcing and 20 mA sinking current with low dropout voltage. Quiescent current is typically 70 µA, dropping to 1.5 µA in shutdown mode. It operates over a -40°C to +125°C range with a maximum input voltage of 16 V.
Feature Summary
- High current output capability allows direct replacement for standard LDO regulators
- Proprietary DigiTrim technology ensures high accuracy and low thermal hysteresis
- Low noise performance suitable for sensitive signal paths
- Integrated enable pin for power management
Applications
- Precision power supplies

Procurement Notes
Verify the specific grade (A or B) and suffix details against the official datasheet before procurement. Confirm that the ordering information matches the required output voltage tolerance and temperature coefficient specifications. Ensure compatibility with the intended PCB layout and thermal requirements for the MSOP package.
Selection Notes
Select this component when high current drive is needed alongside precision referencing. Consider the 6 ppm/°C temperature coefficient and ±0.08% initial error for system accuracy budgets. Evaluate the 70 mA sourcing capacity against load requirements to ensure operation within safe power dissipation limits at elevated temperatures.
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 curvature correction technology for enhanced stability across the operating temperature range.
