LA4500 5.3W 2-Channel AF Power Amplifier

of External Parts C1 (C1) Feedback capacitors Related to low roll-off frequency fL for *3dB (100µF, fL=60Hz). A capacitance value of 47µF to 100µF is recommended. Increasing the capacitance value makes the starting time (ts) later. Decreasing the capacitance value makes the starting time (ts.

LA4500 Features

* Low idling current (20mA/2 channels) enabling prolonged battery life.

* Less dependence of idling current on VCC.

* High power (5.3W typ. ×2).

* High ripple rejection (60dB at steady state). Since filters are arranged in 3 stages (including 1 stage inside the IC) to
