ISL23711 Volatile Digitally Controlled Potentiometer (XDCP™) Terminal Voltage ±3V or ±5V, 128 Taps I2C Serial Interface The Intersil ISL23711 is a digitally controlled potentiometer (XDCP). The device consists of a resistor array, wiper switches, and a control section. The wiper position is controlled by an I2C interface. The potentiometer is implemented by a resistor array composed of 127 resistive elements and a wiper switching network. The wiper terminal can be connected to either end of the resistor array or at any one of the Tap Positions in between, providing 128 steps of resolution between RL and RH. The “position” of the wiper is determined by the value assigned to the volatile Wiper Register (WR). The WR can be directly written to and read from using standard I2C interface protocol. The device is available in either a 10k Ω or 50k Ω version. The device can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including: • Industrial and Automotive Control • Parameter and Bias Adjustments • Amplifier Bias and Control Features •I2C Serial Interface with Hardwire Slave Address Allows up to Four Devices • DCP Terminal Voltage, from V- to VCC • 127 Resistive Elements - Typical RTOTAL tempco ±50ppm/°C - Typical ratiometric tempco ±4ppm/°C - End to end resistance range ±20% - Wiper resistance = 70 Ω typ at VCC = 3.3V • Low Power CMOS - Standby current, 500nA max - Active current, 200 µA max -VCC = 2.7V to 5.5V - V- = -2.7V to -5.5V •RTOTAL Values = 10kΩ, 50kΩ • Volatile Wiper Storage • Package -10 Ld MSOP • Pb-Free Plus Anneal Available (RoHS Compliant) Pinout ISL23711 (10 LD MSOP) TOP VIEW Ordering Information PART NUMBER (BRAND) RESISTANCE OPTION ( Ω) TEMP RANGE (°C) PACKAGE PKG.

Add “-T” suffix for tape and reel. 2. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
