www.DataSheet4U.com MITSUMI Audio MM1407 Audio Monolithic IC MM1407 Outline This audio IC was developed for notebook PCs and allows major reduction of amp circuit board area. (To conform to PC98, includes built-in speaker drive amp, headphone amp, line amp. stereo/monaural switching, DC voltage control electronic volume, watchdog, logic control function.) Features (1) Speaker amp: Stereo BTL output 0.7W (when VCC = 5.0V, RL = 8Ω) (2) Electronic volume control (-60 ~ +20dB). THD = 0.5% (when POUT = 300mW, RL = 8Ω) THD1 = 0.5% (when VOUT = 100mVrms, RL = 16Ω) THD2 = 0.1% (when VOUT = 1VmVrms, RL = 10kΩ) (4) Line amp: Mixes 4 inputs ( 2ch signals and outputs on 3 outputs ( 2ch. Stereo/monaural switching possible on one line. THD = 0.1% (when VOUT = 1Vrms, RL = 10kΩ) (5) Microphone amp: Switch pin selects 1 of 4 inputs (6) Logic control: Speaker, headphone and line amp (including microphone amp and mix amp) logic controllable. Current consumption 300µA during power save mode.
