Product overview

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.
  • All 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
