Features & Applications

The ISL23325TFRUZ-T7A is a dual channel digitally controlled potentiometer with an I2C Bus interface, available in 16 pin TQFN package.

This device integrates two DCP cores, wiper switches and control logic on a monolithic CMOS integrated circuit. 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 I2C bus interface.

Features:

  • Two potentiometers per package
  • 256 resistor taps
  • 100 kΩ total resistance
  • I2C serial interface
    • No additional level translator for low bus supply
    • Three address pins allow up to eight devices per bus
  • Maximum supply current without serial bus activity (standby)
    • 3 μA @ VCC and VLOGIC = 5V
    • 1.7 μA @ VCCand VLOGIC = 1.7V
  • Shutdown Mode
    • Forces the DCP into an end-to-end open circuit and RWi is connected to RLi internally
    • Reduces power consumption by disconnecting the DCP resistor from the circuit
  • Power supply
    • VCC = 1.7V to 5.5V analog power supply
    • VLOGIC = 1.2V to 5.5V I2C bus/logic power supply
  • Wiper resistance: 70Ω typical @ VCC = 3.3V
  • Power-on preset to mid-scale (128 tap position)
  • Extended industrial temperature range: -40°C to +125°C
  • 16 Ld μTQFN packages
  • Pb-free (RoHS Compliant)

Applications:

  • Power supply margining
  • Trimming sensor circuits
  • Gain adjustment in battery powered instruments
  • RF power amplifier bias compensation
