Detailed Description for ADR440ARMZ
Product Overview
The ADR440ARMZ is a fixed series voltage reference from Analog Devices Inc. It provides a 2.048 V output with ±0.15% initial tolerance and a 10 ppm/°C temperature coefficient. The device operates from a 3 V to 18 V input and can deliver up to 10 mA of output current while drawing 3.75 mA of supply current. It is supplied in a surface-mount 8-MSOP package and is specified for a -40°C to 125°C ambient operating temperature. Its 1 µVp-p noise over 0.1 Hz to 10 Hz supports precision analog reference functions in measurement and conversion systems.

Design & Procurement Notes
Select the ADR440ARMZ when a fixed 2.048 V series reference is required with ±0.15% tolerance and 10 ppm/°C coefficient. Verify that the available input voltage remains within 3 V to 18 V and that the connected load does not exceed 10 mA. Include the 3.75 mA supply current in the system power budget. For precision analog paths, consider the 1 µVp-p 0.1 Hz to 10 Hz noise during error analysis. The 8-MSOP surface-mount package requires a compatible PCB footprint and assembly process, and the -40°C to 125°C ambient range should be checked against the final operating environment.
