ISL22419 Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, SPI® Bus, 128 Taps, Wiper Only The ISL22419 integrates a single digitally controlled potentiometer (DCP) and non-volatile memory on a monolithic CMOS integrated circuit. The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wiper is controlled by the user through the SPI serial interface. The potentiometer has an associated volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR) that can be directly written to and read by the user. The contents of the WR controls the position of the wiper. At power-up the device recalls the content of the DCP’s IVR to the WR. The DCP can be used as a voltage divider in a wide variety of applications including control, parameter adjustments, AC measurement and signal processing. Features • 128 resistor taps • SPI serial interface • Non-volatile storage of wiper position • Wiper resistance: 70 Ω typical @ 3.3V • Shutdown mode • Shutdown current 5µA max • Power supply: 2.7V to 5.5V •50k Ω or 10kΩ total resistance • High reliability - Endurance: 1,000,000 data changes per bit per register - Register data retention: 50 years @ ° C • 8 Lead MSOP • Pb-free plus anneal product (RoHS compliant) Pinout ISL22419 (8 LD MSOP) TOP VIEW 1 2 3 4 8 7 6 5 SDO CS SDI Vcc SCK GND SHDN RW T55 ≤ Ordering Information PART NUMBER PART MARKING RESISTANCE OPTION (k Ω) TEMP.
