Frequently Asked Questions
What is the maximum output power the TDA7379 can deliver per channel?
The TDA7379 delivers up to 36W of audio output power per channel at an 18V supply voltage, making it well suited for car audio systems that require high-power stereo amplification from a compact single-package solution.
Which supply voltage range does the TDA7379 operate across, and how does that affect car-radio designs?
The TDA7379 operates across a wide supply voltage range of 8V to 28V DC, accommodating standard 12V automotive electrical systems as well as higher-voltage aftermarket installations up to 28V without requiring additional regulation circuitry.
What protection features are integrated into the TDA7379 to safeguard automotive amplifier circuits?
The TDA7379 integrates thermal shutdown protection that activates above 150°C junction temperature, along with short-circuit protection on the output pins, preventing damage during speaker wiring faults in 4-ohm or 8-ohm load configurations common in car audio.
When is the TDA7379 a better fit than a discrete MOSFET bridge amplifier for a compact car-radio PCB?
The TDA7379 consolidates dual-channel 36W amplification into a single IC with an integrated heatsink tab, reducing component count by more than 20 parts compared to a discrete MOSFET bridge, and shrinking PCB area significantly for tight dashboard assemblies.
