X9460
Low Noise, Low Cost, High End Features, Dual Audio Log Potentiometer
Dual Audio Control Digitally Controlled
Potentiometer (XDCP)
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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
