Overview
ISL23445 NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ISL23425 Quad, 256 Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™) DATASHEET FN7874 Rev 0.
00 June 21, 2011 The ISL23445 is a volatile, low voltage, low noise, low power, 256 tap, quad digitally controlled potentiometer (DCP) with an SPI Bus™ interface.
It integrates four 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, 2, 3) 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 (128 tap position).
The low voltage, low power consumption, and small package of the...
