I just found the datasheet of MCP4452 which is a digital potentiometer. The chip has four potentiometers inside and the interface to the microcontroller is I2C.


Can we select any of the four resistor values (5k Ohm, 10k Ohm, 50k Ohm, 100k Ohm) between the following pins in each of the four potentiometer ?
P0A and P0B
P1A and P1B
P2A and P2B
P3A and P3B

Following are the pins at which the variable resistance can be measured with 7 or 8 bit resolution ?
P0W
P1W
P2W
P3W

yes however stability is relative
