Frequently Asked Questions
What output power and gain does the TDA7297SA provide for a stereo speaker design?
The TDA7297SA delivers up to 15W clip power per channel with a fixed gain of 32 dB, making it suitable for stereo speaker systems where two 4-ohm or 8-ohm drivers need to be driven from a single compact amplifier IC.
How does the TDA7297SA mute function improve user experience in a desktop speaker system?
The TDA7297SA integrates a dedicated mute pin that suppresses audio output pop during power-on and power-off sequences, a critical feature for consumer desktop speakers and clock radios operating on 9V to 18V DC rails.
What is the audio bandwidth of the TDA7297SA and why does it matter for music playback?
The TDA7297SA supports a nominal bandwidth of 20 kHz, covering the full human hearing range from 20 Hz to 20 kHz, ensuring that both low-frequency bass and high-frequency treble content are reproduced accurately at the 15W output stage.
In which compact consumer audio form factors does the TDA7297SA fit most naturally?
The TDA7297SA is housed in a 15-pin SIP package with an integrated heatsink tab, enabling designs as narrow as 12 mm board width, which suits slim desktop speaker enclosures, multimedia soundbars, and compact table radios with 2-channel stereo output.
