Renesas Electronics Corporation Digital Potentiometers X9429WS16IZT1

The X9429WS16IZT1 is a low noise, low power digital potentiometer featuring a single voltage potentiometer configuration 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 data register upon startup. The device operates within a voltage range of 2.7V to 5.5V and has a maximum standby current of less than 3µA. It is available in a 16-lead SOIC package and is RoHS compliant. The X9429WS16IZT1 is suitable for various applications, including audio control, signal processing, and parameter adjustments in electronic circuits.
