ETK PDF Datasheet

General Description ETK145 is a digital audio power amplifier IC with maximum output of 2.1W (RL=4Ω)×1ch. ETK145 has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion rate

General Description ETK2011 is a digital audio power amplifier IC with maximum output of 2.5W (RL=4Ω)×1ch. ETK2011 has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion ra
