供应集成电路LM1458

lm1458是低功耗双运算放大器，宽电源电压范围芯片，单电源 3V - 30V DC电源电压，双电源 正负1.5V - 正负15V DC电源电压。lm1458是通用型双运算放大器，得用正负电源双电源工作，最大电源电压 正负18V。

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.
