TPA3116D2DAD

The TPA3116D2DAD is a 50W Stereo (BTL) Class-D Audio Amp with SpeakerGuard™ for driving speakers up to 100W/2Ω in mono. The high power TPA3116D2 does 2 x 50W/4Ω with a small heat-sink attached to its top side PowerPAD. All three devices share the same footprint enabling a single PCB to be used across different power levels. The TPA3116D2DAD advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences. The TPA3116D2DAD devices are fully protected against faults with short-circuit protection and thermal protection as well as overvoltage, under-voltage and DC protection.

• 2 x 50W into a 4Ω BTL load at 21V
• Efficient class-D operation
• 90% power efficiency combined with low idle loss greatly reduces heat sink size
• Advanced modulation schemes
• AM avoidance
• Up to 1.2MHz switching frequency
• Feedback power-stage architecture with high PSRR reduces PSU requirements
• Programmable power limit
• Differential and single-ended inputs
• Stereo and mono mode with single-filter mono configuration
• Single power supply reduces component count
• Integrated self-protection - overvoltage, under-voltage, over-temperature, DC-detect, short-circuit
• Green product and no Sb/Br

Warnings

IC can be damaged by ESD. We recommend that all ICs be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
