The X9421 is a single digitally controlled potentiometer (XDCP) integrated circuit that provides a low noise, low power solution for various applications.
Key Features:
Single Voltage Potentiometer: 64 resistor taps with a typical wiper resistance of 1500 ohms at 5V.
SPI Serial Interface: Supports write, read, and transfer operations of the potentiometer wiper position.
Non-Volatile Data Registers: Four 6-bit registers for storing multiple wiper positions, with a data retention endurance of 100 years and 100,000 data changes per bit per register.
Power-on Recall: Loads saved wiper position on power-up.
Low Power Operation: 2.7V to 5.5V operation with a standby current of 1uA max at Vcc = 2.7V.
Applications:
Control, parameter adjustments, and signal processing in various systems, including audio, industrial, and wireless applications.
