LA6548

Ordering number : ENN*7886 LA6548 Overview www.DataSheet4U.com Monolithic Linear IC 4CH Bridge (BTL) Driver for CD The LA6548 is a 4CH bridge (BTL) driver with built-in 3.3VREG and RESET for CD players. Functions Bridge connection (BTL) POWER AMP 4CH. Provides MUTE function (Activate for all channels output. When MUTE is H, output is ON.) Built-in 3.3VREG (with external PNP transistor) Built-in RESET circuit (with external capacitor, RESET output delay time can be set.)
