ISL22317 Precision Single Digitally Controlled Potentiometer

DATASHEET ISL22317 Precision Single Digitally Controlled Potentiometer (XDCP™) Low Noise, Low Power, I2C™ Bus, 128 Taps FN6912 Rev 1.00 April 15, 2010 The digitally controlled potentiometer is implemented with a combination of resistor elements and CMOS switches. The position of the wiper is controlled by the user through the I2C bus interface. The potent.

Features

a low end-to-end temperature coefficient of TC_Ref ±10ppm/°C and precise resistance selection. It maintains less than ±1% typical variance from the ideal resistance at each wiper position providing 99% accuracy of selected resistance value. This highly accurate DCP eliminates the need for complex algorit.
