LA4708N Product details

Description

of External Components C1, C4 C2 C3 C5 Input capacitors Decoupling capacitor (ripple filter) Amplifier on time setting capacitor Power supply capacitor 2.2F is recommended.fL can be varied by C1, C4 capacitances to adjust the bass range.Approximately 0.8 second for 33F.Since the on time is proportional to this capacitance, it can be set as desired by varying this capacitance.(Refer to the characteristics curve.) C6, C7, C8, C9 R1 Oscillation blocking capacitors Standby switch current

Features

on-chip protectors and standby switch. Features.
High power : supports total output of 30W  30W (VCC = 13.2V, THD = 30%, RL = 4).
Supports RL = 2 (PO = 30W when VCC = 13.2V, THD = 10%).
Designed for excellent sound quality (fL  10Hz, fH = 130kHz).
NF capacitor-less.
Any on time settable by external capacitor.
Less pop noise.
Standby switch circuit on chip (microprocessor supported).
Various protectors on chip (output-to-ground short/output-to-VCC shor.
