X9116 - Digitally Potentiometer

Description

VH /RH and VL /RL The high (VH/RH) and low (VL/RL) terminals of the X9116 are equivalent to the fixed terminals of a mechanical potentiometer.

The minimum voltage is VSS and the maximum is VCC.

Features

  • Solid-state nonvolatile.
  • 16 wiper taps.
  • 3-wire up/down serial interface.
  • VCC = 2.7V and 5V.

DATASHEET X9116 Low Noise, Low Power, Low Cost Digitally Controlled Potentiometer (XDCP™) FN8160 Rev 3.00 February 3, 2011 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. 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.
