Description
The TS4997 is designed for top-class stereo audio applications. Thanks to its pact and power-dissipation efficient QFN16 package with exposed pad, it suits a variety of 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. 3D effects enhancement is programmed through a two digital input pin interface that allows more flexibility on each output audio sound channel.

Each output channel (left and right), also has its own external controlled standby mode pin to reduce 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.
