The X9421 is a single digitally controlled potentiometer (XDCP) integrated circuit that features a 64-tap resistor array, SPI serial interface, and non-volatile storage of multiple wiper positions.
Key Features
Single voltage potentiometer with 64 resistor taps
SPI serial interface for write, read, and transfer operations of the potentiometer wiper resistance
4 non-volatile data registers for storing multiple wiper positions
Power-on recall loads saved wiper position on power-up
Standby current: 2.5 μA max at Vcc = 2.7V to 5.5V operation
2.5 kΩ, 10 kΩ end-to-end resistance options
Applications
The X9421 can be used in a wide variety of applications, including control, parameter adjustments, and signal processing, such as:
Varying the gain of a voltage amplifier
Providing programmable DC reference voltages for comparators and detectors
Controlling the volume in audio circuits
Trimming out the offset voltage error in a voltage amplifier circuit
