ISL22416
Single Digitally Controlled Potentiometer (XDCP™)
Low Noise, Low Power, SPI® Bus, 128 Taps
The ISL22416 integrates a single digitally controlled
potentiometer (DCP) and non-volatile memory on a
monolithic CMOS integrated circuit.
The digitally controlled potentiometer is implemented with a
combination of resistor elements and CMOS switches. The
position of the wiper is controlled by the user through the SPI
serial interface. The potentiometer has an associated
volatile Wiper Register (WR) and a non-volatile Initial Value
Register (IVR) that can be directly written to and read by the
user. The contents of the WR controls the position of the
wiper. At power-up, the device recalls the contents of the
DCP’s IVR to the WR.
The DCP can be used as a three-terminal potentiometer or
as a two-terminal variable resistor in a wide variety of
applications including control, parameter adjustments, and
signal processing.
