Simple function generator using op amp LM1458
This is function generator using op amp. As usual the function generator will be expensive and difficult.However, this is a simple circuit with only two ICs. This circuit is suitable for experiments. The output is 3 waveform , Square wave signal amplitude 7Vp-p, Triangular wave = 2Vp-vp and sine wave = 2Vp-p all have the frequency 1kHz. We use 2 x LM1458 IC number, is the main equipment this a dual op-amp IC. This circuit uses op-amp 4 section, follow circuit image. The IC1a is square wave generator, Assumed initial, C1 is charging voltage at inverting input pin to zero, …
