Renesas Electronics Corporation Digital Potentiometers X9409WS24ZT1

The X9409WS24ZT1 is a quad digital potentiometer from Quarktwin Technology Ltd., featuring four independently controlled potentiometers integrated into a single CMOS microcircuit. Each potentiometer utilizes a series array of 63 resistive elements, providing 64 tap points for precise adjustments. The device operates via a 2-wire serial interface, allowing for easy integration into various applications. Key specifications include a typical end-to-end resistance of 10kΩ, a wiper resistance of 50Ω at 5V, and the ability to store multiple wiper positions in four nonvolatile data registers. The X9409WS24ZT1 supports a supply voltage range of 2.7V to 5.5V and has a low standby current of less than 1µA. It also features a power-on recall function, ensuring that the last wiper position is restored upon power-up. The device is packaged in a 24-lead TSSOP format and is RoHS compliant, making it suitable for a wide range of electronic applications, including control and signal processing.
