Single, 128-Tap, Low Voltage Digitally Controlled
Potentiometer (XDCP)
ISL23418
The ISL23418 is a volatile, low voltage, low noise, low power,
SPI bus, 128 taps, single digitally controlled potentiometer
(DCP), which integrates DCP core, wiper switches, and control
logic 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
bus interface. The potentiometer has an associated volatile
Wiper Register (WR) that can be directly written to and read by
the user. The contents of the WR controls the position of the
wiper. When powered on, the ISL23418 wiper always
commences at mid-scale (64-tap position).
The low voltage, low power consumption, and small package
size of the ISL23418 make it an ideal choice for use in battery
operated equipment. The ISL23418 has a VLOGIC pin allowing
down to 1.2V bus operation, independent from the VCC value.
This allows for low logic levels to be connected directly to the
ISL23418 without passing through a voltage level shifter.
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.
