X9250TV24-Four Digital Control Potentiometers (XDCP)
The X9250 integrates 4 digitally controlled potentiometers (XDCP) monolithic CMOS integrated circuits. Implement digitally controlled potentiometers using array resistor elements in the 255 series. The connection between each element to the tap point is through the wiper terminal of the switch. The wipers on the position array are controlled by the user through the SPI bus interface. Each potentiometer has its associated volatile wiper counter (WR) and 4 non-volatile data registers (DR0 to: DR3) which can be directly written and read by the user. WR's content controls the position of the wipers though the switch's resistor array. Power West Rail Gundam Review DR0 content. XDCP can be used as a three-terminal potentiometer or two-terminal variable resistor in a wide range of applications including control, parameter adjustment and signal processing.
