Monolithic IC MM1407 Audio
■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
●Speaker amp: Stereo BTL output 0.7W (when VCC = 5.0V, RL = 8Ω)
●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)
●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)
●Microphone amp: Switch pin selects 1 of 4 inputs
●Logic control: Speaker, headphone and line amp (including microphone amp and mix amp) logic controllable. Current consumption 300μA during power save mode.
