Frequently Asked Question

Why does the output signal of my amplifier look like a triangle, when I have a sine wave input?

The signal is most likely slew rate limited. This means that the the output of the amplifier is not fast enough to follow the input signal. An amplifier with a greater slew rate may be required. The minimum required output slew rate for a sine wave is 2pi(Voltage peak * Freq). Please see the Tutorial MT-045,
