Description
YDA138-EZE2 is a high efficient digital audio power amplifier IC that operates with a single 12V power supply. It is suitable for use in various audio applications such as amplifiers and headphones. The IC features a "Pure Pulse Direct Speaker Drive Circuit" which directly drives speakers while reducing distortion and noise, resulting in low distortion rate characteristics and low noise characteristics. It is capable of configuring an audio power amplifier with a maximum output of 10W (RL=8Ω)×2ch or 20W (RL=4Ω)×1ch with just one chip. YDA138-EZE2 supports multi-channel synchronizing operation, carrier frequency switching, sleep function, output muting function, over-current protection, thermal protection, clock stop detection, pop noise reduction, and AM interference measures. It is housed in a 42-pin plastic SSOP package with Pd-free pin lead plating.
