LA4440 - Power Amplifier

General Description

of External Parts C1 (C2)

The low cutoff frequency depends on this capacitor.

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

C3 (C4) Bootstrap Capacitor: If the capacitance value is decreased, the output at low frequen

Key Features

  • Built-in 2 Channels (Dual) Enabling Use in Stereo and Bridge Amplifier.
