TPA3117D2

illustrate

The TPA3117D2 is a 15-watt (per channel) high-efficiency, Class D driver bridge-mounted stereo speaker audio power amplifier. Advanced EMI suppression technology enables the use of inexpensive ferrite bead filters in output while meeting EMC requirements. SpeakerGuard™ speaker protection circuitry, including an adjustable power limiter. An adjustable power limiter allows the user to set a "virtual" voltage rail ratio chip supply limit with a low current value through the speaker.

The TPA3117D2 can drive as few as 4 stereo speakers 。 The TPA3117D2, 90%, high efficiency, eliminates the need for external heatsinks when playing music.

These outputs are also fully protected against prevention_{Consumer Council}Shorts to GND, V and output to output.
