• Signal-to-Noise Ratio (SNR): 80dB (typ)
• Standby Current: <100µA (typ)
• Operating Temperature Range: -40°C to +105°C

Descriptions:

• The TDA7350 is a quad bridge car radio amplifier designed for automotive audio applications.
• It features four independent power amplifiers in a single package, making it suitable for multi-channel audio systems.
• Includes built-in protection circuits against short circuits, thermal overload, and overvoltage.

Features:

• Quad Bridge Configuration: Four independent BTL (Bridge-Tied Load) amplifiers.
• Mute and Standby Functions: Allows power-saving modes.
• Low External Component Count: Simplifies PCB design.
• Thermal Protection: Prevents damage from overheating.
• Short-Circuit Protection: Safeguards the IC and speakers.
• Clip Detector Output: Indicates when the output signal is distorted.

The TDA7350 is commonly used in car audio systems for driving multiple speakers efficiently.
