A. MAIN AMPLIFIER (TPA3110)
a. General Description
17MB70 uses TPA 3110 15-W filter-free stereo Class-D audio power amplifier for main
audio output. The TPA3110D2 is a 15-W (per channel) efficient, Class-D audio power
amplifier for driving bridged-tied stereo speakers. Advanced EMI Suppression Technology
enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC
requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power
limiter and a DC detection circuit. The adjustable power limiter allows the user to set a
"virtual" voltage rail lower than the chip supply to limit the amount of current through the
speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and
shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs.
