Renesas Electronics Corporation Digital Potentiometers X9429YS16

The X9429YS16 is a low noise, low power digital potentiometer from Quarktwin Technology Ltd., featuring a single voltage potentiometer with 64 resistor taps. It operates via a 2-wire serial interface, allowing for write, read, and transfer operations. The device has a typical wiper resistance of 150 ohms at 5V and supports a total pot resistance of 10k ohms. It includes a volatile Wiper Counter Register (WCR) and four non-volatile data registers for storing multiple wiper positions, with power-on recall functionality to load the default register upon startup. The X9429YS16 is designed for a wide range of applications, including audio control, signal processing, and parameter adjustments. It operates within a voltage range of 2.7V to 5.5V and has a maximum standby current of less than 3µA. The device is available in both 16-lead SOIC and 14-lead TSSOP packages, and it is RoHS compliant. With an endurance rating of 100,000 data changes per bit per register and a data retention period of 100 years, this digital potentiometer is suitable for long-term applications.
