TDA7491MV
25 W mono BTL class-D audio amplifier
Features
20 W continuous output power:
RL = 8 Ω, THD = 10% at VCC = 18 V
25 W continuous output power:
RL = 6 Ω, THD = 10% at VCC = 16 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 TDA7491MV is a mono BTL class-D audio
amplifier with single power supply designed for
LCD TVs and monitors.
Thanks to the high efficiency and an
exposed-pad-down (EPD) package no heatsink is
required.
Furthermore, the filterless operation allows a
reduction in the external component count.
The TDA7491MV is pin to pin compatible with the
TDA7491P, TDA7491LP and TDA7491HV for the
left channel as given in Section 6.1 on page 19.
