ECL2011-1W Filterless Non-Clip class-D Audio Power Amplifier

General Description

ECL2011 is a 1W (RL=8Ω) Class-D audio power amplifier. ECL2011 uses the filter-less method allowing the Speaker  to be directly connected to the output and features low-level distortion and noise characteristics. ECL2011 has non-clip function to control gain automatically and prevent output signal from being clipped at the supply voltage. ECL2011 has over-current and over-temperature protection function, under-voltage locked function, as well as EMI noise and pop noise reduction functions. The ECL2011 is available in MSOP8, SOP8 and SOT23-6 packages.
