Renesas Electronics Corporation Data Acquisition - Digital Potentiometers X9409WV24IT1

The X9409WV24IT1 is a quad digitally controlled potentiometer from Quarktwin Technology Ltd., featuring four independent potentiometers integrated into a single CMOS microcircuit. Each potentiometer consists of 63 resistive elements arranged in a series array, providing 64 tap points. The device operates via a 2-wire serial interface, allowing for easy communication and control. It has a typical wiper resistance of 50Oc at 5V and an end-to-end resistance of 10kOc. The X9409WV24IT1 includes four nonvolatile data registers for storing wiper positions, with a power-on recall feature that loads the saved position upon startup. It supports a wide supply voltage range of 2.7V to 5.5V and has a low standby current of less than 1µA. The device is designed for low power consumption and has a data retention capability of up to 100 years, with an endurance rating of 100,000 data changes per bit per register. The product is housed in a 24-lead TSSOP package and is RoHS compliant.
