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 2-pin 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: • LCD contrast control • Parameter and bias adjustments • Industrial and automotive control • Transducer adjustment of pressure, temperature, position, chemical, and optical sensors • Laser Diode driver biasing • Gain control and offset adjustment Features • Volatile Solid-State Potentiometer • 2-pin UP/DN Interface • DCP Terminal Voltage, 2.7V to 5.5V • Tempco 35ppm/°C Typical • 32 Wiper Tap Points • Low Power CMOS - Active current 25µA max. - Supply current 0.3µA • Available RTOTAL Values = 10k50k100k • Temp Range -40°C to +85°C • Packages - 5 Ld SC-70, SOT-23 • Pb-Free Plus Anneal Available (RoHS Compliant) Pinout ISL90460 (5 LD SOT-23, SC-70) TOP VIEW VDD GND U/D RH CSFN8225 Rev 4.00 Page 1 of 8 October 22, 2015

ISL90460 Pin Descriptions RH The ISL90460 contains a digital potentiometer connected as a rheostat or variable resistor. The wiper and one terminal of the digital potentiometer is tied to the RH pin, and the other terminal of the potentiometer is tied to the ground pin (GND). The resistance from the RH pin to ground will vary with the potentiometer setting; at the highest setting, the resistance will be the maximum (Rtot), at the lowest setting it will be a minimum. Up/Down (U/D) The U/D input controls the direction of the wiper movement and whether the counter is incremented or decremented. Chip Select (CS) The device is selected when the CS input is LOW. The current counter value is stored in volatile memory when CS is returned HIGH. When CS is high, the device is placed in low power standby mode. Principles of Operation There are two sections of the ISL90460: the input control, counter and decode section; and the resistor array. The input control section operates just like an up/down counter. The output of this counter is decoded to turn on a single electronic switch connecting a point on the resistor array to the wiper output. The resistor array is comprised of 31 individual resistors connected in series. At either end of the array and between each resistor is an electronic switch that transfers the connection at that point to the wiper. The wiper is connected to the RH terminal, forming a variable resistor from RH to GND. The direction of the wiper movement is defined when the device is selected. If during CS transition from High to Low the U/D input is LOW, the wiper will move down on each rising edge of U/D toggling. Similarly, the wiper will move up on each rising edge of U/D toggling if, during CS transition from High to Low, the U/D input is High. The wiper, when at either fixed terminal, acts like its mechanical equivalent and does not move beyond the last position. That is, the counter does not wrap around when clocked to either extreme. If the wiper is moved several positions, multiple taps are connected to the wiper for tSETTLE (U/D to RH change). The 2-terminal resistance value for the device can temporarily change by a significant amount if the wiper is moved several positions. CS U/D RH tCU tCI tIL tIH tIC tSETTLE FIGURE 2.
