品牌:Apexone
封裝:DFN8
批號(hào):10+
數(shù)量:200000
描述:GENERAL DESCRIPTION
The A7013 is a cost-effective 2.5W mono filter-free
class-D audio power amplifier, designed with Apexone
proprietary EFSTM (Enhanced Feedback Structure)
technology and architecture. The device can drive
speakers as low as 4Ω.
Apexone EFSTM technology has the advantage over
traditional PWM class D audio power amplifier and
increases the performance dramatically for audio
solutions. It reduces THD and EMI effectively and offers
low distortion across both the wide audio output power
range and the full audio frequency domain. The device
utilizes a fully differential architecture and a full-bridged
output.
The A7013 features high PSRR of 81dB, low THD+N of
0.02%, and higher than 88dB SNR. Short circuit and thermal
overload protection prevents the devices from being damaged
during over current conditions. Integrated internal mute
control function suppresses pop/click sound. The high
efficiency of the A7013 eliminates the need of external heat
sinks and extends battery life.
KEY FEATURES
