ISL22416 Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, SPI® Bus, 128 Taps The ISL22416 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 contents of the DCP’s IVR to the WR. The DCP can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing. Features • 128 resistor taps • SPI serial interface • Non-volatile storage of wiper position • Wiper resistance: 70 Ω typical @ V CC = 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 @ T ≤ +55°C • 10 Ld MSOP and 10 Ld TDFN package • Pb-free (RoHS compliant) Pinout ISL22416 (10 LD MSOP) TOP VIEW ISL22416 (10 LD TDFN) TOP VIEW 1 2 3 4 5 6 10 9 8 7 SDO SHDN CS SDI VCC SCK GND RL RW RH SDO SHDN CS SDI VCC SCK GND RL RW RH 1 2 3 4 5 6 10 9 8 7 O Ordering Information PART NUMBER (Note) PART MARKING RESISTANCE OPTION (k Ω) TEMP.

Please refer to TB347 for details on reel specifications. NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. Data Sheet September 9, 2009 |
