Features & Applications
The ISL23328WFRUZ-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
- 128 resistor taps
- 10 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 (64 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
