The TDA8354Q circuit diagram provides detailed pin function descriptions. This information is sourced from the Venus D2908F. Here's a breakdown of the key pins and their functions:


Pin 1: 0.3V – Input signal or reference voltage.
Pin 2: 7.9V – Current feedback input, used for monitoring current flow in the circuit.
Pin 3: 8.4V – Voltage conversion input, typically connected to a regulated power source.
Pin 4: 16V – Main power supply input for the IC.
Pin 5: 8.4V – Voltage output (bottom), often used for powering internal components.
Pin 6: 0V – Ground connection, essential for stable operation.
Pin 7: 48V – Additional power supply line, possibly for high-voltage applications.
Pin 8: 0V – Another ground point, ensuring proper electrical reference.
Pin 9: 8.4V – Voltage output (top), used for different stages of the circuit.
Pin 10: 16V – Secondary power supply, may be used for specific sub-circuits.
Pin 11: 1.2V – Field push input (-), part of the feedback or control mechanism.
Pin 12: 1.2V – Field push input (+), complementary to Pin 11.
Pin 13: 2V – Compensation resistor input, used for adjusting gain or stability.

Understanding these pin functions is crucial for designing or troubleshooting circuits using the TDA8354Q. Whether you're working on audio amplifiers, power management systems, or other electronic projects, this data helps ensure correct implementation and performance.
