AN6210是日本松下公司生产的立体声磁带录放音放大集成电路,工作电压范围为5～12 V。内含两路麦克(MIC)放大器、两路放音前置放大器、两路线路放大器、两路自动增益控制(AGC)通道以及静噪电路等。采用28个脚双列直插式 DIP 封装,各脚功能如表1所示。AN6210典型应用电路及引脚电压如图1所示。与其他同类产品相比,其显著特点是:线路放大器是共用的,而麦克放大器及放音前置放大器则彼此独立不共用。线路放大器分别接受麦克信号(录音状态)、磁带信
AN6210 is Panasonic’s stereo tape recording and playback amplifier integrated circuits, operating voltage range of 5 ~ 12 V. Contains two microphone (MIC) amplifier, two preamplifier, two line amplifiers, two automatic gain control (AGC) channels and squelch circuits. 28 feet dual DIP DIP package, the function of each pin as shown in Table 1. AN6210 typical application circuit and pin voltage shown in Figure 1. Compared with other similar products, its notable features are: line amplifier is shared, while the microphone amplifier and playback amplifier are independent of each other are not shared. Line amplifiers accept the microphone signal (recording state), tape letter
