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