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 potentiometer has an associated volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR) that can be directly written to and r.

ISL22317 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 al
