1.the internal circuit and pin functions of AN6210AN6210 contains two lines of microphone amplifiers, two lines of reproducing preamplifiers, two lines of wiring amplifiers and auto gain control lines. In Figure 1 is the internal circuit of it. Comparing with other circuits, its chief advantages are that the wiring amplifiers are public but the recording/reproducing pre-stage is not, and it is divided into an independent reproducing preamplifier and microphone amplifier. AN6210 is in 28-lead dual in-line package. 2. Principle parameters of AN6210
