TDA7491LP

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.

主な特徴

5 W + 5 W continuous output power:R_L= 8 Ω, THD = 10% at V_CC= 9 V
