描述 Description

The TDA7491P is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.

特性 Features

■ 10 W + 10 W continuous output power:

RL= 6 Ω, THD = 10 at VCC = 11 V

■ 9.5 W + 9.5 W continuous output power:

RL = 8 Ω, THD = 10 at VCC = 12 V

■ Wide range single supply operation (5 V - 18 V)

■ High efficiency (η= 90)

■ Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB

■ Differential inputs minimize common-mode noise

■ Filterless operation

■ No ‘pop’ at turn-on/off

■ Standby and mute features

■ Short-circuit protection

■ Thermal overload protection

■ Externally synchronizable
