50 W + 50 W dual BTL class-D amplifier

Datasheet - production data

Description

The TDA7492 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-up

(EPU) package, only a simple heatsink is

required.

with exposed pad up

Features

 50 W + 50 W continuous output power at

THD = 10% with RL = 6  and VCC = 25 V

 40 W + 40 W continuous output power at

THD = 10% with RL = 8  and VCC = 25 V

 Wide-range single-supply operation (8 - 26 V)

 High efficiency ( = 90%)

 Four selectable, fixed gain settings of

nominally 21.6 dB, 27.6 dB, 31.1 dB and

33.6 dB

 Differential inputs minimize common-mode

noise

 Standby and mute features

 Short-circuit protection

 Thermal overload protection

 Externally synchronizable

 ECOPACK®, environmentally friendly package
