The TDA7297 is a dual-bridge amplifier IC designed for audio applications, particularly in stereo amplifiers for multimedia systems, TVs, and other audio playback devices. This IC integrates two amplifiers in a single package, making it convenient for stereo audio amplification. Here are some key features and specifications of the TDA7297:
Dual-Bridge Amplifier: The TDA7297 consists of two bridge amplifiers, making it suitable for stereo applications where separate amplification is required for the left and right audio channels.
Output Power: The TDA7297 is capable of delivering a moderate power output, typically in the range of 15 watts per channel into a 4-ohm load or 10 watts per channel into an 8-ohm load. The actual power output depends on factors such as the operating conditions and thermal considerations.
Class-AB Operation: The amplifier operates in Class-AB mode, combining the efficiency of Class-B amplifiers with the low distortion of Class-A amplifiers.
Wide Supply Voltage Range: The IC can operate with a wide supply voltage range, typically from around 6V to 18V. This flexibility allows compatibility with various power supply configurations.
Low Distortion: The TDA7297 is designed to provide low harmonic distortion in the amplified audio signal, contributing to high audio fidelity.
Thermal Shutdown Protection: The IC includes thermal shutdown protection to prevent damage due to excessive heat. If the temperature exceeds a certain threshold, the amplifier will shut down until it cools down.
Short Circuit Protection: The TDA7297 may include short circuit protection to prevent damage in case of a short circuit on the output.
Fixed Gain: The IC typically has a fixed gain, simplifying the design of the amplifier circuit.
Package: The TDA7297 is commonly available in a multiwatt-15 package, which is a compact package suitable for audio amplifier applications.
Applications: The TDA7297 is used in stereo audio amplifier applications where a moderate power output is required. It is commonly found in multimedia speakers, TVs, and small audio amplifiers.
