Single, Low Voltage Digitally Controlled Potentiometer

(XDCP™)

ISL23315

Features

• 256 resistor taps

The ISL23315 is a volatile, low voltage, low noise, low power, I C

™

Bus , 256 Taps, single digitally controlled potentiometer (DCP),

• I C serial interface

which integrates DCP core, wiper switches and control logic on

a monolithic CMOS integrated circuit.

- No additional level translator for low bus supply

- Two address pins allow up to four devices per bus

The digitally controlled potentiometer is implemented with a

combination of resistor elements and CMOS switches. The

position of the wipers are controlled by the user through the

• Power supply

- V = 1.7V to 5.5V analog power supply

I C bus interface. The potentiometer has an associated

- V

LOGIC

= 1.2V to 5.5V I C bus/logic power supply

volatile Wiper Register (WR) that can be directly written to and

read by the user. The contents of the WR controls the position

of the wiper. When powered on, the ISL23315’s wiper will

always commence at mid-scale (128 tap position).

• Wiper resistance: 70Ω typical @ V = 3.3V

• Shutdown Mode - forces the DCP into an end-to-end open

circuit and R is shorted to R internally

The low voltage, low power consumption, and small package

of the ISL23315 make it an ideal choice for use in battery

• Power-on preset to mid-scale (128 tap position)

• Shutdown and standby current <2.8µA max

operated equipment. In addition, the ISL23315 has a V

LOGIC

pin allowing down to 1.2V bus operation, independent from the

value. This allows for low logic levels to be connected

• DCP terminal voltage from 0V to V

• 10kΩ, 50kΩ or 100kΩ total resistance

• Extended industrial temperature range: -40°C to +125°C

• 10 Ld MSOP or 10 Ld µTQFN packages

• Pb-free (RoHS compliant)

directly to the ISL23315 without passing through a voltage

level shifter.

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.

Applications

• Power supply margining

• RF power amplifier bias compensation

• LCD bias compensation

• Laser diode bias compensation
