ISL95711 Digitally Controlled Potentiometer (XDCP™) Terminal Voltage ±2.7V or ±5V, 128 Taps I2C Serial Interface The Intersil ISL95711 is a digitally controlled potentiometer (XDCP). The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a 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). This register has an associated non-volatile Initial Value Register (IVR). The value stored in the IVR will be written into the WR at power-up, allowing wiper position recall after power interruption. The WR and the IVR can be directly written to and read from using standard I2C interface protocol. The device is available in either a 10k Ω or 50kΩ 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 Pinout ISL95711 (10 LD MSOP) TOP VIEW Features • Non-Volatile Solid-State Potentiometer •I2C Serial Interface with Hardwire Slave Address Allows Up to Four Devices per bus • DCP Terminal Voltage, from V- to VCC • 128 Wiper Tap Points - Wiper position can be stored in nonvolatile memory and recalled on power-up • 127 Resistive Elements - Typical Rtotal tempco ±50ppm/°C - Ratiometric Tempco ±4ppm/°C - End to end resistance range ±20% • Low Power CMOS - Standby current, 1µA - Active current, 200 µA max -VCC = 2.7V to 5.5V - V- = -2.7V to -5.5V • High Reliability - Endurance, 200,000 data changes per bit - Register data retention, 50 years •RTOTAL Values = 10kΩ, 50kΩ • Package -10 Ld MSOP - Pb-free plus anneal (RoHS compliant) GND SCL SDA V- 1 2 3 4 10 9 8 7 RH RW A0 VCC 5 RL 6 A1 Ordering Information PART NUMBER (Notes 1, 2) PART MARKING RESISTANCE OPTION ( Ω) TEMP.

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. Data Sheet September 5, 2006 |
