LAG668是日本MITSUM1公司继单片放音机电路LAG665之后,推出的升级产品,除具有LAG665相同功能外,又具备如下特点。第一,重低音电路(适当选取外围元件,可组成超重低音效果)。第二,电机稳速电路采用特别设计的马达噪音抑制电路,并设有电机快进开关。第三,工作电压3V,消耗电流18mA,左右声道误差为0dB。用LAG668设计组成的放音机,不仅外围元件少, LAG668 is the Japanese MITSUM1 company following the monolithic playback circuit LAG665, the introduction of the upgraded products, in addition to the same LAG665 features, but also has the following characteristics. First, the bass circuit (appropriate selection of external components, can be composed of bass effect). Second, the motor speed circuit using a specially designed motor noise suppression circuit, and the motor fast-forward switch. Third, the operating voltage 3V, current consumption 18mA, left and right channel error of 0dB. LAG668 design with a playback device, not only less peripheral components,
