Product Introduction

TPA3111D1 10W mono Class D audio power amplifier with SpeakerGuard™

illustrate

The TPA3112D1 is a 25-watt speaker efficient driving side-by-side, Class D audio power amplifier. Advanced electromagnetic interference suppression technology enables the use of inexpensive ferrite bead filters while meeting EMC requirements. The SpeakerGuard™ speaker protection system includes an adjustable power limiter and DC detection circuitry. 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. The DC detection circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitor is damaged or the input on the shorts is present.

The TPA3112D1 can drive as low as 4 mono speakers 。
