DS3923T+

Current Regulation/Management Overview

The DS3923T+ is a digital potentiometer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features three independent wiper positions controlled via an I²C-compatible serial interface. The device offers non-volatile memory to retain resistance settings during power loss, ensuring immediate availability of configured values upon re-powering. It operates within a supply voltage range of 2.7V to 5.5V and supports end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. The component is housed in an 8-lead TSSOP package suitable for surface-mount applications requiring precise analog signal adjustment.

Current Regulation/Management Procurement Notes

Verify the specific suffix designation against official datasheets to confirm resistance value and package type. Ensure compatibility with I²C bus voltage levels and check for authorized distribution channels to avoid counterfeit components. Confirm RoHS compliance status as indicated on the manufacturer's documentation prior to procurement.

Current Regulation/Management Selection Notes

Select this component when multiple independent variable resistors are required in a compact form factor. Consider the total number of available tap positions and the required resolution for the specific application. Verify that the operating voltage range aligns with the system's power supply constraints and that the interface protocol matches the microcontroller or controller capabilities.

Current Regulation/Management Part Context

This part belongs to the family of digital potentiometers designed for replacing mechanical potentiometers in space-constrained designs. It provides reliable electronic adjustment without moving parts, enhancing durability and enabling remote configuration through digital interfaces. The inclusion of non-volatile memory distinguishes it from volatile counterparts, maintaining state across power cycles.

Current Regulation/Management Replacement Considerations

Check pinout compatibility and electrical specifications against existing solutions. Verify that substitute parts support the same I²C addressing scheme and resistance tolerances. Ensure thermal performance and package dimensions meet the original design requirements.
