Low Noise, Low Power, I
The ISL22326 integrates two digitally controlled potentiometers
(XDCP) 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
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’s IVR to the corresponding WRs.
The DCPs can be used as three-terminal potentiometers or
as two-terminal variable resistors in a wide variety of
applications including control, parameter adjustments, and
signal processing.
