1.What is TDA7492P?
The TDA7492P 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 heatsink is required.
2.TDA7492P vs TDA7492?
The difference between TDA7492 and TDA7492P lies in the overcurrent threshold which is 6A and 4.2A respectively. The lower current threshold of TDA7492P dictates a higher typical load impedance of 8 ohm compared to the 6 ohm of the TDA7492. The difference is dictated by a lower maximum operating temperature probably due to the TDA7492P being produced using a cheaper technique or cheaper materials in the construction or both.
