Renesas Electronics Corporation Digital Potentiometers X9428YV14I

The X9428YV14I is a digitally controlled potentiometer featuring a 2-wire serial interface and a register-oriented format. It allows direct read, write, and transfer of wiper positions, with the capability to store up to four positions per potentiometer. The device operates with power supply voltages ranging from 2.7V to 5.5V for VCC and V+, and -2.7V to -5.5V for V-. It is designed for low power consumption, with a standby current of less than 1µA, making it suitable for battery-operated applications. This potentiometer integrates a 10kOc resistor array with a resolution of 64 taps, and it is available in a 14-lead TSSOP package. The X9428YV14I is characterized by high reliability, with an endurance of 100,000 data changes per bit per register and a data retention period of 100 years. It is RoHS compliant and can be used in various applications such as control, parameter adjustments, and signal processing.
