MAX4902 Maxim, MAX4902 Datasheet - Page 9

• Manufacturer Part Number: MAX4902
• Description: The MAX4901–MAX4905 switches feature negative signal capability that allows signals below ground to pass through without distortion
• Manufacturer: Maxim

Audible clicks and pops are caused when a step DC
voltage is switched into the speaker. By automatically
discharging the side that is not connected, any resid-
ual DC voltage is removed, thereby reducing the clicks
and pops.
Power-Supply Sequencing and Overvoltage
Caution: Do not exceed the absolute maximum rat-
ings because stresses beyond the listed ratings
may cause permanent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V
analog signals, especially if the analog signal is not
current-limited.
