TS4984 Datasheet | STMicroelectronics

Description The TS4984 has been designed for top of the class stereo audio applications. Thanks to its pact 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 10n A per channel. The device also features an internal thermal shutdown protection. The gain of each channel can be configured by external gain setting resistors.
