DATASHEET ISL23445 FN7874 Rev 0.00 Quad, 256 Tap, Low Voltage Digitally Controlled Potentiometer (XDCP) June 21, 2011 The ISL23445 is a volatile, low voltage, low noise, low power, 256 Features tap, quad digitally controlled potentiometer (DCP) with an SPI Four potentiometers per package Bus interface. It integrates four DCP cores, wiper switches and control logic on a monolithic CMOS integrated circuit. 256 resistor taps Each digitally controlled potentiometer is implemented with a 10k 50k or 100k total resistance combination of resistor elements and CMOS switches. The SPI serial interface position of the wipers are controlled by the user through the - No additional level translator for low bus supply SPI bus interface. Each potentiometer has an associated volatile Wiper Register (WRi, i = 0, 1, 2, 3) that can be directly - Daisy Chaining of multiple DCPs written to and read by the user. The contents of the WRi Maximum supply current without serial bus activity controls the position of the wiper. When powered on, the wiper (standby) of each DCP will always commence at mid-scale (128 tap - 5A V and V = 5V CC LOGIC position). -2uA V and V = 1.7V CC LOGIC The low voltage, low power consumption, and small package Shutdown Mode of the ISL23445 make it an ideal choice for use in battery - Forces the DCP into an end-to-end open circuit and RWi is operated equipment. In addition, the ISL23445 has a V LOGIC connected to RLi internally pin allowing down to 1.2V bus operation, independent from the - Reduces power consumption by disconnecting the DCP V value. This allows for low logic levels to be connected CC resistor from the circuit directly to the ISL23445 without passing through a voltage level shifter.
