What is slew rate formula?
Slew rate = 2 π f V. Where. slew rate is measured in volts / second, although actual measurements are often given in v/µs. f = the highest signal frequency, Hz. V = the maximum peak voltage of the signal.
How do you calculate gain bandwidth?
Open-loop Frequency Response Curve For example, from the graph above the gain of the amplifier at 100kHz is given as 20dB or 10, then the gain bandwidth product is calculated as: GBP = A x BW = 10 x 100,000Hz = 1,000,000.
Why IC 555 is called Timer IC?
The 555 Timers name comes from the fact that there are three 5kΩ resistors connected together internally producing a voltage divider network between the supply voltage at pin 8 and ground at pin 1.
