TDA7491P

2 x 10-watt dual BTL class-D audio amplifier

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

Description

The TDA7491P is a dual BTL class-D audio

amplifier with single power supply designed for

LCD TVs and monitors.

Thanks to the high efficiency and

exposed-pad-down (EPD) package no separate

heatsink is required.

Furthermore, the filterless operation allows a

reduction in the external component count.

The TDA7491P is pin-to-pin compatible with the

TDA7491LP and TDA7491HV.
