Product Introduction

TPA3117D2 15W stereo filterless Class D amplifier

illustrate

This TPA3117D2 is a 15-watt (per channel) efficient, Class D drive bridge-mounted stereo speaker audio power amplifier. Advanced electromagnetic interference suppression technology enables the use of inexpensive ferrite bead filters while meeting EMC requirements. SpeakerGuard™ speaker protection circuit, including an adjustable power limiter. The adjustable power limiter allows the user to set a "virtual" voltage rail than the chip supply limit with a low current value through the speaker.

This TPA3117D2 can drive up to four stereo speakers 。 This TPA3117D2 is 90% efficient, eliminating the need for external heat sinks when music is needed.

These outputs also provide adequate protection, preventing the Consumer Council from shorts to GND, V, and outputs to outputs.
