Overview
ISL23448 NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ISL23428 Quad, 128 Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™) DATASHEET FN7905 Rev 0.
00 August 19, 2011 The ISL23448 is a volatile, low voltage, low noise, low power, 128 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 (64 tap position).
The low voltage, low power consumption, and small package of th...
