• Operating Frequency: 300kHz to 500kHz (adjustable)
• Standby Current: < 1mA
• Mute Function: Yes
• Thermal Protection: Yes
• Short-Circuit Protection: Yes

Descriptions:

• The TDA7499 is a dual BTL (Bridge-Tied Load) class-D amplifier designed for high-power audio applications.
• It operates in a single-ended supply configuration, making it suitable for consumer audio systems, home theaters, and professional amplifiers.
• The device includes built-in protection features such as thermal shutdown and short-circuit protection.

Features:

• High Efficiency: Class-D operation reduces power dissipation.
• Flexible Supply Voltage: Works across a wide input range (10V–36V).
• Adjustable Switching Frequency: Allows optimization for EMI performance.
• Standby and Mute Modes: Low-power consumption when inactive.
• Minimal External Components: Simplifies PCB design.
• Surface-Mount Package: HTSSOP32 (PowerSSO-36) for compact designs.
