Based on TDA2009 power amplifier application line circuit diagram

This article introduces the application circuit diagram of the TDA2009 power amplifier. The maximum operating power supply voltage is 28V, the output power is 2×10W, the typical operating power supply voltage is 24V, and the normal operating voltage is 8-28V. The normal operating voltage means that the integrated circuit can work normally within this range. Many parameters are tested according to typical working voltages.
