MAX9875规格书详情
General Description
The MAX9875 combines a high-efficiency Class D audio power amplifier with a stereo Class AB capacitor less DirectDrive® headphone amplifier. Maxim’s 3rd generation, filterless Class D amplifier with active emissions limiting technology provides Class AB performance with Class D efficiency.
The MAX9875 delivers up to 725mW from a 3.7V supply into an 8Ω load with 87 efficiency to extend battery life. The filterless modulation scheme combined with active emissions limiting circuitry and spread-spectrum modulation greatly reduces EMI while eliminating the need for output filtering used in traditional Class D devices.
