FEATURES APPLICATIONS
2• 15-W/ch into an 8-Ω Loads at 10% THD+N • Televisions
From a 16-V Supply • Consumer Audio Equipment
• 10-W/ch into 8-Ω Loads at 10% THD+N From a
13-V Supply DESCRIPTION
• 30-W into a 4-Ω Mono Load at 10% THD+N The TPA3110D2 is a 15-W (per channel) efficient,
From a 16-V Supply Class-D audio power amplifier for driving bridged-tied
stereo speakers. Advanced EMI Suppression
• 90% Efficient Class-D Operation Eliminates Technology enables the use of inexpensive ferrite Need for Heat Sinks bead filters at the outputs while meeting EMC
• Wide Supply Voltage Range Allows Operation requirements. SpeakerGuard™ speaker protection
from 8 V to 26 V circuitry includes an adjustable power limiter and a
DC detection circuit. The adjustable power limiter • Filter-Free Operation
allows the user to set a "virtual" voltage rail lower
• SpeakerGuard™ Speaker Protection Includes than the chip supply to limit the amount of current
Adjustable Power Limiter plus DC Protection through the speaker. The DC detect circuit measures
• Flow Through Pin Out Facilitates Easy Board the frequency and amplitude of the PWM signal and
Layout shuts off the output stage if the input capacitors are
damaged or shorts exist on the inputs. • Robust Pin-to-Pin Short Circuit Protection and
Thermal Protection with Auto Recovery Option The TPA3110D2 can drive stereo speakers as low as
4 Ω. The high efficiency of the TPA3110D2, 90%, • Excellent THD+N / Pop-Free Performance
eliminates the need for an external heat sink when
• Four Selectable, Fixed Gain Settings playing music.
• Differential Inputs
The outputs are also fully protected against shorts to
GND, VCC, and output-to-output. The short-circuit
protection and thermal protection includes an autorecovery feature.
