Source: InternetPublisher:黄土马家 Keywords: Oscillator Updated: 2024/09/26
Figure 8 is a circuit of an audio square wave oscillator composed of 1/4LM339. Changing C1 can change the frequency of the output square wave. In this circuit, when C1=0.1uF, f=53Hz; when C1=0.01uF, f=530Hz; when C1=0.001uF, f=5300Hz.
LM339 can also form a high-voltage digital logic gate circuit and can directly interface with TTL and CMOS circuits.
