ISL95810 Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power I2C Bus, 256 Taps The ISL95810 integrates a digitally controlled potentiometer (XDCP) 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 I2C bus 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 content 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 three-terminal potentiometer or as two-terminal variable resistor in a wide variety of applications including control, parameter adjustments, and signal processing. Features • 256 resistor taps - 0.4% resolution •I2C serial interface • Wiper resistance: 70 Ω typical @ 3.3V • Non-volatile storage of wiper position • Standby current 5µA max • Power supply: 2.7V to 5.5V •50k Ω, 10kΩ total resistance • High reliability - Endurance: 200,000 data changes per bit per register - Register data retention: 50 years @ T ≤ 75°C • 8 Ld MSOP and 8 Ld TDFN packaging • Pb-free plus anneal available (RoHS compliant) Pinout ISL95810 (8 LD MSOP) TOP VIEW ISL95810 (8 LD TDFN) TOP VIEW Ordering Information PART NUMBER PART MARKING RTOTAL (k Ω) TEMP RANGE (°C) PACKAGE ISL95810WIU8* AIU 10 -40 to 85 8 Ld MSOP ISL95810WIU8Z* (Note) -40 to 85 8 Ld MSOP (Pb-free) ISL95810WIRT8Z* (Note) -40 to 85 8 Ld 3 x 3 TDFN (Pb-free) ISL95810UIU8* AIT 50 -40 to 85 8 Ld MSOP ISL95810UIU8Z* (Note) AOK -40 to 85 8 Ld MSOP (Pb-free) ISL95810UIRT8Z* (Note) -40 to 85 8 Ld 3 x 3 TDFN (Pb-free) *Add “-T” suffix for tape and reel. NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are 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. 1 2 3 4 5 6 7 SDA SCL 8 WP RW RL RH VCC GND 2 3 4 1 7 6 5 8 SDA SCL WP GND RW RL RH VCC Data Sheet October 7, 2005 |
