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.

Two potentiometers per package
Wiper resistance of 70Ω typical VCC 3.3V
Power-on pre-set to mid-scale (128 tap position)
Extended industrial temperature range of -40°C to +125°C
Pb-free (RoHS compliant)
