The chart shows a function generator circuit composed of 555 timer. The circuit consists of a CH7555 timer and some transistors and RC components. It can generate triangle wave, square wave, sine wave, sawtooth and square wave sweep simultaneously. Ramp can be positive or negative. The frequency of various waveforms is adjustable from 0.1Hz ~ 100kHz, the amplitude of square wave is 5 ~ 15V, it can directly drive TTL circuits (power supply is 5V). Nonlinear ramp is below 1%, sine wave distortion is less than 3%.
