SLOS650B – AUGUST 2009 – REVISED SEPTEMBER 2009 6-W FILTER-FREE STEREO CLASS-D AUDIO POWER AMPLIFIER WITH SPEAKERGUARD™ 2 • 6-W/ch into an 8-Ω Loads at 10% THD+N From a 10-V Supply The TPA3113D2 is a 6-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied • 12-W into a 4-Ω Mono Load at 10% THD+N stereo speakers. Advanced EMI Suppression From a 10-V Supply Technology enables the use of inexpensive ferrite • 87% Efficient Class-D Operation Eliminates bead filters at the outputs while meeting EMC Need for Heat Sinks requirements. SpeakerGuard™ speaker protection • Wide Supply Voltage Range Allows Operation circuitry includes an adjustable power limiter and a from 8 V to 26 V DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage rail lower • Filter-Free Operation than the chip supply to limit the amount of current • SpeakerGuard™ Speaker Protection Includes through the speaker. The DC detect circuit measures Adjustable Power Limiter plus DC Protection the frequency and amplitude of the PWM signal and • Flow Through Pin Out Facilitates Easy Board shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs. Layout • Robust Pin-to-Pin Short Circuit Protection and The TPA3113D2 can drive stereo speakers as low as Thermal Protection with Auto Recovery Option 4 Ω. The high efficiency of the TPA3113D2, 87%, eliminates the need for an external heat sink when • Excellent THD+N / Pop-Free Performance playing music. • Four Selectable, Fixed Gain Settings The outputs are also fully protected against shorts to • Differential Inputs GND, VCC, and output-to-output. The short-circuit protection and thermal protection includes an auto-recovery feature. • Televisions • Consumer Audio Equipment • Monitors Figure 1.
