X9429
X9429 is Single Digitally Potentiometer manufactured by Renesas.
Low Noise/Low Power/2-Wire Bus Single Digitally Controlled Potentiometer (XDCP™)
FN8248 Rev 4.00 October 16, 2015
The X9429 integrates a single digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.
The digital controlled potentiometer is implemented using 63 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through switches. The position of the wiper on the array is controlled by the user through the 2-wire bus interface. The potentiometer has associated with it a volatile Wiper Counter Register (WCR) and a four non-volatile Data Registers that can be directly written to and read by the...
