MAX9879規(guī)格書詳情
General Description
The MAX9879 combines a high-efficiency stereo Class D audio power amplifier with a stereo capacitor-less DirectDrive? headphone amplifier. Maxim’s filterless class D amplifiers with active emissions limiting technology provide Class AB performance with Class D efficiency.
The Class D power amplifier delivers up to 715mW from a 3.7V supply into an 8Ω load with 88 efficiency to extend battery life. The filterless modulation scheme combined with active emission limiting circuitry and spread-spectrum modulation greatly reduces EMI while eliminating the need for output filtering used in traditional Class D devices.
