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.

Key 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
