Slew rate is a critical parameter in operational amplifiers (op-amps) that limits the maximum rate of voltage change that can be generated by the op-amps output circuitry. It is measured as voltage relative to time, and the typical unit used in datasheets is volts per microsecond (V/µs) . Slew rate is the maximum rate at which an amplifier can respond to the sudden change of input level. It can distort or limit any signal if the slew rate requirement is exceeded. Slew rate changes with the change in voltage gain and is generally specified at unity (+1) gain condition. The slew rate of an electronic circuit is defined as the rate of change of the voltage per unit of time, and the units for slew rate are Volts per second or V/µs. The slew rate is a temperature-dependent parameter, and it is measured by applying a step signal to the input stage of the op-amp and measuring the rate of change occurs at the output from 10% to 90% of the output signal’s amplitude. The slew rate is strongly influenced by the amount of compensation capacitance. In certain applications where speed is required and the output needs to change quickly, the slew rate of the operational amplifier can have a significant effect on the overall performance of the electronic circuit, and the design needs to accommodate this.
