October 20, 2015 Single Volatile 32-tap XDCP Digitally Controlled Potentiometer (XDCPв„ў)
The Intersil ISL90462 is a digitally controlled potentiometer
(XDCP). Configured as a variable resistor, the device
consists of a resistor array, wiper switches, a control section,
and volatile memory. The wiper position is controlled by a 2pin Up /Down interface.
The potentiometer is implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. Between each element and at either end are tap
points accessible to the wiper terminal. The position of the
wiper element is controlled by the CS and U/D inputs.
The device can be used in a wide variety of applications
including: Features Volatile Solid-State Potentiometer 2-pin UP/DN Interface DCP Terminal Voltage, 2.7V to 5.5V Tempco 35ppm/В°C Typical 32 Wiper Tap Points Low Power CMOS
