X9015 Low Noise, Low Power, Volatile Single Digitally Controlled (XDCP™) Potentiometer 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. •RTOTAL = 10kΩ, 50kΩ • Packages 8 Ld SOIC, 8 Ld MSOP • Pb-free plus anneal available (RoHS compliant) Pinout Block Diagram VCC CS INC U/D RH/VH VSS 1 2 3 4 8 7 6 5 X9015 SOIC/MSOP RL/VL RW/VW 5-Bit Up/Down Counter Control Circuitry One of Decoder Resistor Array RH/VH U/D INC CS Transfer Gates Thirty VCC VSS RL/VL RW/VW Control Up/Down (U/D) Increment (INC) Device Select (CS) VCC (Supply Voltage) VSS (Ground) RH/VH RW/VW RL/VL General Detailed 0 1 2 28 29 30 31 Two Data Sheet August 31, 2006 |
