About the TS4997

The TS4997 is designed for top-class stereo audio applications. Thanks to its compact 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.

Key features of the TS4997 include:
