1. The internal circuit and pin functions of KA9270 KA9270 contains the impedance buffer, low-pass filter, de-weight control motor, basic pole voltage circuit, whose internal circuit is shown in figure 1-1. The IC is in 20-pin dual line structure, which has two forms marked with suffix letters, the one without suffix is dual in-line package, and the other one with D suffix is flat dual line package, the pin functions of them are the same, see as table 1-1.Figure 1-1 the internal circuit of KA9270/D
