DATASHEET ISL90462 FN8230 Rev 4.00 Single Volatile 32-tap XDCP Digitally Controlled Potentiometer (XDCP) October 20, 2015 The Intersil ISL90462 is a digitally controlled potentiometer Features (XDCP). Configured as a variable resistor, the device Volatile Solid-State Potentiometer consists of a resistor array, wiper switches, a control section, and volatile memory. The wiper position is controlled by a 2- 2-pin UP/DN Interface pin Up /Down interface. DCP Terminal Voltage, 2.7V to 5.5V The potentiometer is implemented by a resistor array Tempco 35ppm/C Typical composed of 31 resistive elements and a wiper switching 32 Wiper Tap Points network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the Low Power CMOS wiper element is controlled by the CS and U/D inputs. - Active current, 25A max. - Supply current 0.3A The device can be used in a wide variety of applications including: Available R Values = 10k50k100k TOTAL LCD contrast control Temperature Range -40C to +85C Parameter and bias adjustments Packages - 6 Ld SC-70, SOT-23 Industrial and Automotive Control Pb-Free Plus Anneal Available (RoHS Compliant) Transducer adjustment of pressure, temperature, position, chemical, and optical sensors Pinout Laser Diode driver biasing ISL90462 (SOT23, SC70) Gain control and offset adjustment TOP VIEW RH VDD RW GND CS U/D Ordering Information PART NUMBER PART MARKING R (K) TEMP RANGE (C) PACKAGE (Tape and Reel) PKG.
