This is a simple AF amplifier based on TDA2003, which is an amplifier of AF with a nominal output power of
- 10W at a load 2 Ohms,
- 5W at a load 4 Ohms,
- 2.5W at load 8 Ohms
Frequency range 20-20000 Hz.
Chip TDA2003 has a built-in thermal protection and protection against short circuits on the output. The advantages of IC are a small quantity of additional elements, a low current consumption, not critical to the power supply (~ 1A, DC 8..16.5 V).
Allows short-term work at case temperature up to 100 degrees.
