Dual, 128-Tap, Low Voltage Digitally Controlled

Potentiometer (XDCP™)

ISL23328

Features

• Two potentiometers per package

• 128 resistor taps

The ISL23328 is a volatile, low voltage, low noise, low power,

128-Tap, dual digitally controlled potentiometer (DCP) with an

I C Bus™ interface. It integrates two DCP cores, wiper switches

• 10kΩ, 50kΩ or 100kΩ total resistance

and control logic on a monolithic CMOS integrated circuit.

• I C serial interface

Each 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 I C

- No additional level translator for low bus supply

- Three address pins allow up to eight devices per bus

bus interface. Each potentiometer has an associated volatile

Wiper Register (WRi, i = 0, 1) that can be directly written to and

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

of the wiper. When powered on, the wiper of each DCP will

always commence at mid-scale (64 tap position).

• Power supply

- V = 1.7V to 5.5V analog power supply

- V

LOGIC

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

• Maximum supply current without serial bus activity

(standby)

The low voltage, low power consumption, and small package

of the ISL23328 make it an ideal choice for use in battery

operated equipment. In addition, the ISL23328 has a V

LOGIC

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

• Shutdown Mode

value. This allows for low logic levels to be connected

- Forces the DCP into an end-to-end open circuit and RWi is

connected to RLi internally

directly to the ISL23328 without passing through a voltage

level shifter.

- Reduces power consumption by disconnecting the DCP

resistor from the circuit

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.

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

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

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

• 14 Ld TSSOP or 16 Ld UTQFN packages

• Pb-free (RoHS Compliant)

Applications

• Power supply margining

• Trimming sensor circuits

• Gain adjustment in battery powered instruments

• RF power amplifier bias compensation
