TDA7491HV

20 W + 20 W dual BTL class-D audio amplifier

Features

! 20 W + 20 W continuous output power:

RL = 8 Ω, THD = 10% at VCC = 18 V

! Wide range single supply operation (5 V - 19 V)

! High efficiency (

η = 90%)

! Four selectable, fixed gain settings of 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 TDA7491HV is a dual BTL class-D audio

amplifier with single power supply designed for

LCD TVs and monitors.

Thanks to the high efficiency and slug-down

package no heatsink is required.

Furthermore, the filterless operation allows a

reduction in the external component count.

The TDA7491HV is pin to pin compatible with the

TDA7491P and TDA7491LP.
