Description
This is 18W Hi-Fi AMPLIFIER AND 35W DRIVER.
The TDA2030 is a monolithic IC in Pentawatt package intended for use as low frequency class AB amplifier. With Vsmax=44V it is particularly suited for more reliable applications withou regulated supply and for 35W driver circuits using lowcost complementary pairs. The TDA2030 provides high output current and has very low harmonic and cross-over distortion.
Further the device incorporates a short circuit protection system somprising an arrangement for automatically limiting the dissipated power to as to keep the working point of the output transistors within their safe operating area. A conventional thermal system is also included.
A Hi-Fi (High Fidelity) amplifier, also known as a stereo amplifier or audio amplifier, is an electronic device designed to amplify low-power audio signals to a level suitable for driving high-quality speakers. It is a crucial component in high-fidelity audio systems, aiming to reproduce sound with accuracy and clarity, preserving the original audio signal as faithfully as possible.
The primary goal of a Hi-Fi amplifier is to provide sufficient power to drive speakers while maintaining signal integrity and minimizing distortion. It takes the low-level audio signals from a source, such as a preamplifier or audio source device, and amplifies them to a level suitable for driving loudspeakers.
