Low Noise, Low Power, SPI
The ISL22414 integrates a single digitally controlled
potentiometer (DCP), control logic 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 control the position of the
wiper. At power-up the device recalls the contents of the
DCP’s IVR to the WR.
The ISL22414 also has 14 General Purpose non-volatile
registers that can be used as storage of lookup table for
multiple wiper position or any other valuable information.
The ISL22414 features a dual supply that is beneficial for
applications requiring a bipolar range for DCP terminals
between V- and VCC.
The DCP can be used as three-terminal potentiometer or as
two-terminal variable resistor in a wide variety of applications
including control, parameter adjustments, and signal
processing.
