What is slew rate in power supplies?
If the signal is a sine wave and the slew rate is 10000V/sec, the rise time will take 1 second. Therefore, high-voltage amplifiers are required to have high slew rate performance. This page provides descriptions of Slew Rate in Power Supplies.
What is slew rate in a low power op amp?
Some low-power op amps express slew rate in volts per millisecond, V/ms. The data sheet slew rate (SR) parameter is the rate of change of the output voltage with a large input signal and unity gain setup (unless specifically stated otherwise). This single value is often the only obvious information about slew rate in the data sheet.
What is slew rate?
Slew rate defines the maximum rate of change per unit time for either output voltage or output current. Magna-Power's limits on slew rate produce a non-linear rise time effect. Magna-Power's slew rate specifications characterize the power supply's rise-time in response to a programmed voltage or current change.
What are slew rate specifications?
The slew rate specifications apply to any transition in voltage or current. For example, the same slew rate would apply for a programmed transition from 0 to 50% load as from 0 to 100%. The rise time for voltage and current can be model using Equation 1:
What is output slew rate?
The output slew rate (SR) can be varied from -B/CC to +B/CC. The result of B/CC is the slew rate that is specified on the data sheet. For some op amps, the positive and negative slew rate can be a little different; in this example the slower rate is recorded. The SR in the data sheet is always the magnitude of SR, ignoring polarity.
What is the slew rate of a high-voltage amplifier?
The slew rate is based on the slower of ramp up and ramp down. In a high-voltage amplifier, a signal with an input voltage of 1 V is amplified to 10 kV, etc., for output. If the signal is a sine wave and the slew rate is 10000V/sec, the rise time will take 1 second. Therefore, high-voltage amplifiers are required to have high slew rate performance.
