Description

The TS4985 has been designed for top-class stereo audio applications. Thanks to its compact and power-dissipation efficient flip-chip package, it suits various applications.

With a BTL configuration, this audio power amplifier is capable of delivering 1.2W per channel of continuous RMS output power into an 8? load @ 5V.

Each output channel (left and right), has an external controlled standby mode pin (STDBYL & STDBYR) 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.
