• 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
The TPA3110D2 is a 15-W (per channel) efficient,
• 30-W into a 4-Ω Mono Load at 10% THD+N
Class-D audio power amplifier for driving bridged-tied
From a 16-V Supply

through the speaker. The DC detect circuit measures
• Flow Through Pin Out Facilitates Easy Board the frequency and amplitude of the PWM signal and
shuts off the output stage if the input capacitors are
Layout
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 auto-
recovery feature.
