DATASHEET
ISL23428
Dual, 128-Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™)
The ISL23428 is a volatile, low voltage, low noise, low power,
128-tap, dual digitally controlled potentiometer (DCP) with an
SPI Bus™ interface. It integrates two DCP cores, wiper switches
and control logic on a monolithic CMOS integrated circuit.
Each digitally controlled potentiometer is implemented with a
combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
SPI bus interface. Each potentiometer has an associated
volatile Wiper Register (WRi, i = 0, 1) that can be directly written
to and read by the user. The contents of the WRi controls the
position of the wiper. When powered on, the wiper of each DCP
will always commence at mid-scale (64 tap position).
The low voltage, low power consumption, and small package
of the ISL23428 make it an ideal choice for use in battery
operated equipment. In addition, the ISL23428 has a V
LOGIC
pin allowing down to 1.2V bus operation, independent from the
V
CC
value. This allows for low logic levels to be connected
directly to the ISL23428 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.
