Filter-less 2W Class-D amp. / DAC Suitable Effectors for Small Speakers
Description
ML26211 is a audio DAC built-in with filterless 4Ω 2W Class-D amplifier, low consumption power DAC, and OKI SEMICONDUCTOR's unique LoudSound technology for improving sound of small speakers. LoudSound is Oki Semicondutor's expertise which is the sound quality improvement technology most suited for devices with small speakers and realizes about 3dB volume-up compared with nothing processed.
In addition, as high peformance PLL is built-in, it can generate clock with widely between 32kHz and 27MHz and audio clock with 44.1kHz, etc. This LSI is best for the equipment of playback-only such as portable navigations, ETC, audio DAC, etc.
