LA4440 - Power Amplifier

General Description

of External Parts C1 (C2)

Feedback capacitor : The low cutoff frequency depends on this capacitor.

If the capacitance value is increased, the starting time is delayed.

Bootstrap capacitor : If the capacitance value is decreased, the output at low frequencies goes lower.

Key Features

  • Built-in 2 channels (dual) enabling use in stereo and bridge amplifier.
