Overview
DATASHEET X95840 Quad Digital Controlled Potentiometers (XDCP™) Low Noise/Low Power/I2C Bus/256 Taps FN8213 Rev 2.
00 July 5, 2006 The X95840 integrates four digitally controlled potentiometers (XDCP) on a monolithic CMOS integrated circuit.
The digitally controlled potentiometers are 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.
Each potentiometer has an associated volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR), that can be directly written to and read by the user.
The contents of the WR controls the position of the wiper.
At power up the device recalls the contents of the four DCP’s IVR to the corresponding WRs.
The DCPs can be used as three-terminal potentiometers or as two-terminal variable resistors in a wide variety of applications including control, parameter adjustments, and signal processing.
