LA4708 Product details

Description

of External Components C1, C4 C2 C3 Input capacitors Decoupling capacitor (ripple filter) Amplifier on time setting capacitor Power supply capacitor Oscillation blocking capacitors Use polyester film capacitors (Mylar capacitors) with good temperature characteristics.(R2, R3, R4, and R5 used jointly.) Since stability may be affected slightly by the pattern layout, etc., 0.1 µF or more is recommended.10 kΩ is recommended (when the applied voltage for the standby switch is 2.5 V to 13.2 V).This

Features

on-chip protectors and standby switch. The LA4708 is also pin-compatible with the LA4705NA (car stereo-use 17 W two-channel power IC), and can be substituted for the LA4705NA for higher power. (When the board is shared, pins 1 and 9 must be left open. ) Package Dimensions unit: mm 3109-SIP18H [LA4708] Features . High power: supports total output of 30 W + 30 W = 13.2 V, THD = 30%, R = 4 Ω) . (V Supports R = 2 Ω (P = 30 W when V = 13.2 V, THD = 10%) . Designed for excellent sound quality (f <.
