Description
The TDA7491LP 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 TDA7491LP is pin-to-pin compatible with the TDA7491P and TDA7491HV.
Features
■ 5 W + 5 W continuous output power: RL = 8 Ω, THD = 10 at VCC = 9 V
■ 5 W + 5 W continuous output power: RL = 4 Ω, THD = 10 at VCC = 6.6 V
■ Wide range single supply operation (5 V - 14 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
