TDA2051 is a monolithic integrated circuit in Pentawatt package, intended for use as an audio class AB amplifier. It is able to provide up to 40W typ. into 4 ohm load @ THD = 10%, VS = ±18V, f = 1KHz and up to 33W into 8ohm load @ THD = 10%, VS = ±22V, f = 1KHz. Moreover, the TDA2051 delivers typically 60W music power into 4 ohm load over 1 sec at VS= 22.5V, f = 1KHz. The very low harmonic and crossover distortion performances make the device the most suitable for Hi-Fi field application.
The TDA2051 is a monolithic integrated circuit in a Pentawatt package designed for Hi‑Fi audio applications. It delivers up to 40 W typical into a 4 Ω load with low total harmonic distortion and can operate from single or split supplies.
Ordering numbers for the device are TDA2051V and TDA2051.H. The low external component count and efficient heat‑sink design make it suitable for compact stereo amplifiers.
