Monolithic IC MM1407

Audio 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.

Package
