Description
The TS4982 features a stereo loudspeaker driver
and a ground-referenced stereo headphone
driver. An independent standby mode pin allows
the TS4982 to simultaneously drive both output
drivers. Operating on a single 5 V supply, the
TS4982 delivers 2 W (typ.) output power into a
4
Ω load at 1% THD+N.
The TS4982 features a PC beep input, three
levels of 3D stereo enhancement and 4-step gain
control using two digital input pins. Minimum
external components make the TS4982 well-
suited for notebook and other hand-held sound
equipment. It also has an internal thermal
shutdown (150° C) and output short circuit
protection mechanism.
