TDA7388 STMICROELECTRONICS

The TDA7388 is a quad bridge car audio amplifier integrated circuit (IC) capable of delivering up to 4×41 watts of output power to four channels. Here’s an overview of its features and specifications:

• Type: Quad Bridge Car Audio Amplifier IC
• Power Output: Capable of delivering up to 41 watts RMS per channel into a 4-ohm load with a supply voltage of 14.4V.
• Configuration: Provides four independent amplifier channels, making it suitable for car audio systems with multiple speakers or channels.
• Bridge-Tied Load (BTL) Configuration: Each amplifier channel can be configured in a bridge-tied load configuration for higher power output into a single speaker.
• Voltage Supply Range: Typically operates from a single supply voltage ranging from 8V to 18V, making it suitable for automotive applications where battery voltage can vary.
• Low Distortion: Offers low total harmonic distortion (THD) and intermodulation distortion (IMD) for high-quality audio reproduction.
• Protection Features: May include built-in protection features such as thermal shutdown, overvoltage protection, and short-circuit protection to safeguard the IC and connected components.
• Package: It’s commonly available in multiwatt-15 (MW15) packages or similar packages with varying pin configurations.
• Temperature Range: It typically operates across a wide temperature range to withstand automotive environments, often from -40°C to 105°C.

The TDA7388 is specifically designed for automotive audio applications, such as car stereos, amplifiers, and speaker systems. Its high power output, low distortion, and robust protection features make it a popular choice for powering speakers in vehicles while maintaining high audio quality and reliability.
