Single, 128-taps Low Voltage Digitally Controlled

Potentiometer (XDCP™)

ISL23318

Features

The ISL23318 is a volatile, low voltage, low noise, low power,

• 128 resistor taps

I C Bus™, 128 Taps, single digitally controlled potentiometer

• I C serial interface

(DCP), 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 ISL23318’s wiper will

always commence at mid-scale (64 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

• Power-on preset to mid-scale (64 tap position)

• Shutdown and standby current <2.8µA max

The low voltage, low power consumption, and small package

of the ISL23318 make it an ideal choice for use in battery

operated equipment. In addition, the ISL23318 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 UTQFN packages

• Pb-free (RoHS compliant)

directly to the ISL23318 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

• Gain adjustment in battery powered instruments

• Trimming sensor circuits

• Power supply margining

• RF power amplifier bias compensation
