廬
Bus, 128 Taps
The ISL22346WMVEP integrates four digitally controlled
potentiometers (DCP) and non-volatile memory on a
monolithic CMOS integrated circuit.
The digitally controlled potentiometers are implemented with
a combination of resistor elements and CMOS switches. The
position of the wipers are controlled by the user through the
I
2
C bus interface. Each 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 two
DCP鈥檚 IVR to the corresponding WRs.
The DCPs can be used as a three-terminal potentiometers
or as a two-terminal variable resistors in a wide variety of
applications including control, parameter adjustments and
signal processing.
