TDA7491P
2 x 10-watt dual BTL class-D audio amplifier
Features
■ 10 W + 10 W continuous output power:
R_L = 6 Ω, THD = 10% at V_CC = 11 V
■ 9.5 W + 9.5 W continuous output power:
R_L = 8 Ω, THD = 10% at V_CC = 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
PowerSSO-36 with
exposed pad down
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.
