X9460 双音频控制数控电位器（数字电位器TM）

The X9460 integrates two digitally controlled potentiometer (xDCP) on a monolithic CMOS integrated circuit. The two xDCPs can be used as stereo gain controls in audio applications. Read/Write operations can directly access each channel independently or both channels simultaneously. Increment/Decrement can adjust each channel independently or both channels simultaneously.

The X9460 contains a zero amplitude wiper switching circuit that delays wiper changes until the next zero crossing of the audio signal.

The digitally controlled potentiometer is implemented using 31 polysilicon resistors in a log array. Between each of the resistors are tap points connected to the wiper terminal through switches. The xDCPs are designed to minimize wiper noise to avoid pops and clicks during audio volume transitions. The position of the wiper on the array is controlled by the user through the 2-wire serial bus interface.

Power-up reset the wiper to the mute position.
