X9409WV24Z

Digital Potentiometers Overview

The X9409WV24Z is a quad digitally controlled potentiometer (XDCP) IC manufactured by Renesas Electronics. It integrates four independent 10 kΩ resistive networks, each featuring 64 taps for precise resistance adjustment. The device utilizes a non-volatile wiper memory to retain the last set position upon power loss. Control is managed via a standard two-wire serial interface compatible with I²C protocols. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes a typical operating current of 100 µA. The component is housed in a 24-pin TSSOP package and supports linear taper characteristics.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during soldering processes.

Digital Potentiometers Selection Notes

Select this model when a quad-channel solution with non-volatile retention is required. Verify that the 10 kΩ resistance value and 64-step resolution align with circuit design specifications. Ensure the system logic levels are compatible with the two-wire serial interface. Consider thermal dissipation limits if operating near maximum temperature boundaries.

Digital Potentiometers Part Context

This component belongs to the X9409 series of low-power CMOS digitally controlled potentiometers. It serves as an electronic alternative to mechanical potentiometers, offering improved reliability and programmability. The device is part of Renesas' portfolio of mixed-signal control components designed for industrial and consumer applications.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9409 variants such as X9409WS24Z for package differences. Verify pinout compatibility before substituting with similar quad digital potentiometers from other manufacturers. Ensure interface protocol support matches the existing system architecture.
