STMicroelectronics TS4985
The TS4985 has been designed for top-class stereo audio applications. With a BTL configuration, this audio power amplifier is capable of delivering 1.2W per channel of continuous RMS output power into an 8Ω 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.| Part No. | TS4985 |
