MAX9877規(guī)格書詳情

General Description

The MAX9877 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 MAX9877 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.
