ISL23315TFUZ-T7A, Digital Potentiometer 256-Position Linear Serial-I2C 10 Pin, MSOP

The Renesas digitally controlled potentiometer is a volatile, low voltage, low noise, low power, I2C Bus, 256 taps, single digitally controlled potentiometer (DCP), which integrates DCP core, wiper switches and control logic on a monolithic CMOS integrated circuit. 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 I2C bus interface.

Wiper resistance of 70Ω typical VCC 3.3V
Shutdown Mode - forces the DCP into an end-to-end open circuit and RW is shorted to RL internally
Power-on pre-set to mid-scale (128 tap position)
Shutdown and standby current <2.8μA max
Extended industrial temperature range of -40°C to +125°C
Pb-free (RoHS compliant)
