Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power I C

Bus, 256 Taps

The ISL95810 integrates a digitally controlled potentiometer

(XDCP) on a monolithic CMOS integrated circuit.

Features

• 256 resistor taps - 0.4% resolution

The digitally controlled potentiometer is implemented with a

combination of resistor elements and CMOS switches. The

position of the wiper is controlled by you through the I C 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. 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.

• I C serial interface

• Wiper resistance: 70Ω typical at 3.3V

• Non-volatile storage of wiper position

• Standby current 5µA max

• Power supply: 2.7V to 5.5V

• 50kΩ, 10kΩ total resistance

The DCP can be used as a 3-terminal potentiometer or as a

2-terminal variable resistor in a wide variety of applications

including control, parameter adjustments, and signal

processing.

• High reliability

- Endurance: 200,000 data changes per bit per register

- Register data retention: 50 years at T  +75°C

• 8 Ld MSOP and 8 Ld TDFN packaging
