X9015

DATASHEET X9015 Low Noise, Low Power, Volatile Single Digitally Controlled (XDCP™) Potentiometer FN8157 Rev 6.00 August 14, 2015 The Intersil X9015 is a 32 tap potentiometer that is volatile. The device consists of a string of 31 resistors that can be programmed to connect the RW/VW wiper output with any of the nodes between the connecting resistors. The connection point of the wiper is determined by information communicated to the device on the 3-wire port. The 3-wire port changes the tap position by a falling edge on the increment pin. The direction the wiper moves is determined by the state of the up/down pin. The wiper position at power up is Tap #15. The X9015 can be used in a wide variety of applications that require a digitally controlled variable resistor to set analog values. Features 32 taps Three-wire up/down serial interface VCC = 2.7V–5V Operating ICC = 50µA max. Standby current = 1µA max.
