TDA2051 Audio Power Amplifier Datasheet
The TDA2051 is a monolithic integrated circuit in a Pentawatt package designed for Hi‑Fi audio applications. It can deliver up to 40 W typical into a 4 Ω load at 1 kHz with THD ≤10% when powered from +18 V, and up to 33 W into an 8 Ω load at +22 V.
The device includes several protection features such as short‑circuit protection (output to ground) and thermal shutdown. Its low external component count and efficient heat‑sink design make it suitable for compact stereo equipment.
