DATASHEET X9116 FN8160 Rev 3.00 Low Noise, Low Power, Low Cost Digitally Controlled Potentiometer (XDCP) February 3, 2011 The Intersil X9116 is a digitally controlled nonvolatile Features potentiometer designed to be used in trimmer applications. Solid-state nonvolatile The pot consists of 15 equal resistor segments that connect 16 wiper taps to the wiper pin through programmable CMOS switches. The tap position is programmed through a 3-wire up/down serial 3-wire up/down serial interface port. The last position of the wiper is stored in a nonvolatile V = 2.7V and 5V CC memory location which is recalled at the time of power up of the device. Active current < 50A max. The wiper moves through sequential tap positions with Standby current < 5A max. inputs on the serial port. A falling edge on INC (bar) causes R = 10k TOTAL the tap position to increment one position up or down based Packages: 8 Ld MSOP, 8 Ld SOIC on whether the U/D (bar) pin is held high or low. Pb-free plus anneal available (RoHS compliant) The X9116 can be used in many applications requiring a variable resistance. In many cases it can replace a Pinout mechanical trimmer and offers many advantages such as SOIC/MSOP temperature and time stability as well as the reliability of a solid state solution.

Add T* suffix for tape and reel. Please refer to TB347 for details on reel specifications. 2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is 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. 3. For Moisture Sensitivity Level (MSL), please see device information page for X9116. For more information on MSL please see techbrief TB363. Pin Descriptions Pin Descriptions SYMBOL DESCRIPTION V /R and V /R H H L L The high (V /R ) and low (V /R ) terminals of the X9116 are V /R Wiper Terminal H H L L W W equivalent to the fixed terminals of a mechanical V /R Low Terminal L L potentiometer. The minimum voltage is V and the maximum SS V Ground SS is V . CC V Supply Voltage CC V /R W W U/D Up/Down Control Input R /R is the wiper terminal and is equivalent to the movable w w terminal of a mechanical potentiometer. The position of the INC Increment Control Input wiper within the array is determined by the control inputs. The CS Chip Select Input wiper terminal series resistance is typically 200 to 400 depending upon V . CC Up/Down (U/D) The U/D input controls the direction of the wiper movement and whether the counter is incremented (up) or decremented (down). Increment (INC) The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the U/D input. Chip Select (CS) The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete the X9116 will be placed in the low power standby mode until the device is selected once again.
