Features & Applications

The ISL23318WFRUZ-T7A is a volatile, low voltage, low noise, low power digitally controlled potentiometer. It is available in 10 pin TQFN package.

This device integrates DCP core, wiper switches and control logic on a monolithic CMOS integrated circuit. It 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. The low voltage, low power consumption, and small package of the ISL23318 make it an ideal choice for use in battery operated equipment.

Features:

128 resistor taps
I2C serial interface
- No additional level translator for low bus supply
- Two address pins allow up to four devices per bus
Power supply
- VCC = 1.7 V to 5.5 V analog power supply
- VLOGIC = 1.2 V to 5.5 V I2C bus/logic power supply
Wiper resistance: 70 Ω typical @ VCC = 3.3 V
Shutdown Mode forces the DCP into an end-to-end open circuit and RW is shorted to RL internally
Power-on preset to mid-scale (64 tap position)
Shutdown and standby current <2.8 μA max
DCP terminal voltage from 0V to VCC
10 kΩ total resistance
Extended industrial temperature range: -40°C to +125°C
10 Ld UTQFN packages
Pb-free (RoHS compliant)

Applications:

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