Frequently Asked Questions
What output power does the TDA7563AH deliver per channel?
The TDA7563AH delivers 50 W nominal output power per channel across 4 channels, for a total of 200 W system output. This is achieved with less than 10% total harmonic distortion, making it suitable for high-fidelity car audio and consumer amplifier applications.
Which package does TDA7563AH use, and how does it handle thermal dissipation in a car audio design?
The TDA7563AH is housed in an HZIP-27 package with an exposed metal tab for heatsink mounting, enabling efficient thermal dissipation of high power levels. The package supports direct attachment to chassis or dedicated heatsinks, critical when driving 4 x 50 W loads in confined automotive enclosures.
How does the I2C diagnostic interface on the TDA7563AH benefit system designers?
The I2C diagnostic interface allows the host microcontroller to read real-time fault status, including overtemperature and short-circuit conditions, without needing separate discrete fault lines. This simplifies PCB routing and enables software-controlled protection responses, reducing overall system BOM in 4-channel, 50 W automotive amplifier designs.
What audio bandwidth does the TDA7563AH support, and is it sufficient for full-range speaker systems?
The TDA7563AH supports a nominal bandwidth of 22 kHz, covering the full audible frequency range from 20 Hz to 22 kHz. This makes it well-suited for driving full-range and woofer speakers in car audio and home theater systems without frequency-limiting the audio signal.
