increased, the unit gain bandwidth can be calculated to select an appropriate op amp. This parameter is used for selection of small signal processing operations. Pendulum rate (Conversion Rate) SR:When the op amp is connected to a closed loop, a large signal (including a step signal) is input to the input end of the op amp, and the output speed of the op amp is increased from the output end of the op amp. During the conversion, the input level of the op amp is in the switch state, so the feedb
