TS4984：2 x 1W stereo audio power amplifier with active low standby mode
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 8Ω 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.
