DATASHEET ISL22316 FN6186 2 Rev 3.00 Single Digitally Controlled Potentiometer (XDCP) Low Noise, Low Power I C August 14, 2015 Bus, 128 Taps The ISL22316 integrates a single digitally controlled Features potentiometer (DCP) and non-volatile memory on a 128 resistor taps monolithic CMOS integrated circuit. 2 I C serial interface The digitally controlled potentiometer is implemented with a - Two address pins, up to four devices/bus combination of resistor elements and CMOS switches. The position of the wipers are controlled by the user through the Non-volatile storage of wiper position 2 I C bus interface. The potentiometer has an associated Wiper resistance: 70 typical V = 3.3V CC volatile Wiper Register (WR) and a non-volatile Initial Value Shutdown mode Register (IVR) that can be directly written to and read by the user. The contents of the WR controls the position of the Shutdown current 5A max wiper. At power-up, the device recalls the contents of the Power supply: 2.7V to 5.5V DCPs IVR to the WR. 50kor 10k total resistance The DCP can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of High reliability applications including control, parameter adjustments, and - Endurance: 1,000,000 data changes per bit per register signal processing. - Register data retention: 50 years T +55C 10 Ld MSOP or 10 Ld TDFN package Pb-free (RoHS compliant) Pinouts ISL22316 ISL22316 (10 LD MSOP) (10 LD TDFN) TOP VIEW TOP VIEW O 1 10 VCC SCL SCL 1 10 VCC SDA RH 2 9 SDA 2 9 RH A1 3 RW 8 3 8 A1 RW 4 7 RL A0 A0 4 7 RL SHDN 5 6 GND 5 SHDN 6 GND Ordering Information PART NUMBER PART RESISTANCE OPTION TEMP.
