Description
The TS4984 has been designed for top of the
class stereo audio applications. Thanks to its
compact and power dissipation efficient QFN
package, it suits various applications.
With a BTL configuration, this Audio Power
Amplifier is capable of delivering 1W per channel
of continuous RMS output power into an 8
load
@ 5V.
An externally controlled standby mode control
reduces the supply current to less than 10nA per
channel. The device also features an internal
thermal shutdown protection.
The gain of each channel can be configured by
external gain setting resistors.

Applications
■ Cellular mobile phones
■ Notebook computers & PDAs
■ LCD monitors & TVs
■ Portable audio devices
