Ολοκληρωμένο LA4743K
Ολοκληρωμένο LA4743K το οποίο είναι τροφοδοτικό και τελικός ενισχυτής εξόδου.
Power 45W? 4-ch Audio Power IC
Overview The LA4743B is a 45 W 4-channel power amplifier IC for car stereo systems. It features a built-in bridge circuit and the ability to radically reduce the number of external components required. It is also pin compatible with the LA4743A, which differs in the amount of gain provided. Features • Maximum output power: 45 W ? 4 channels (VCC = 14.4 V, 4 ? load, 1 kHz) • 40 W ? 4 channels (VCC = 13.7 V, 4 ? load, 1 kHz) • Requires only seven external components and does not require an oscillation prevention RC circuit, a noise filter, or a BS capacitor. Functions • Muting function • Built-in standby switch • Full complement of built-in protection circuits, including protection from shorting to VCC, shorting to ground, load shorting, overvoltages, and overheating
