... REV 1.1.4 11/13/00 S YSTEM X9110 ™ DESCRIPTION The X9110 integrates a single digitally controlled potentiometer integrated circuit. The digital controlled potentiometer is implemented using 1023 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 SPI bus interface ...

... This can help to reduce system pin count. Array Description The X9110 is comprised of a resistor array (Figure 1). The array contains the equivalent of 1023 discrete resistive segments that are connected in series. The physical ends of each array are equivalent to the fixed terminals of a mechanical potentiometer (R inputs) ...

... Bit 5 Bit compare of the address bit is required for the X9110 to successfully continue the command sequence. Only the device whose slave address matches the incoming device address sent by the master executes the instruction. The A0 input can be actively driven by CMOS input signals or tied used to set the device to either read or write mode ...

... X9110 – Preliminary Information Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a potentiometer. (2) Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer measure of the error in step size. ...
