The STMicroelectronics TDA2009A is a class AB dual Hi-Fi audio power amplifier engineered for high-quality stereo sound performance. Housed in a compact Multiwatt-11 package, this amplifier is suitable for various audio devices including Hi-Fi systems, music centers, and multimedia speakers.
Key specifications include a supply voltage range of 8V to 28V, delivering up to 10W per channel into an 8Ω load with 1% THD, or 12.5W x 2 into a 4Ω load. It operates within a wide temperature range of -40°C to 150°C and features a frequency response from 20 Hz to 20 kHz.
The TDA2009A boasts high current capability up to 3.5A, built-in protection against short circuits and thermal overloads, and a low quiescent current of 50 mA. Its design minimizes external components, simplifying mounting and reducing costs.
Applications for the TDA2009A include stereo audio systems, television audio outputs, multimedia speaker systems, car audio, portable audio equipment, and public address systems.
The supply voltage range is 8V to 28V.
Up to 10W per channel into 8Ω loads at 1% THD, and up to 12.5W per channel into 4Ω loads.
The operating temperature range is -40°C to 150°C.
The TDA2009A is available in a Multiwatt-11 package.
Total harmonic distortion is typically 0.1% at 1W, 1 kHz.
The frequency response is 20 Hz to 20 kHz.
The voltage gain is 30 dB.
