What is the maximum frequency at which an op-amp can be used?

WebIf you use an op amp with a low slew rate, the shape of the waveform will change and distortion will worsen. Its maximum output frequency (f max) can be calculated from the slew rate.For simplicity, we will first explain the case of using op-amp in unity gain. The slew rate (SR) is expressed as: SR = ΔV o / Δt r or ΔV o / Δt f WebIt is interesting to consider the effects of a chopper amplifier on low frequency 1/f noise. If the chopping frequency is considerably higher than the 1/f corner frequency of the input noise, the chopper-stabilized amplifier continuously nulls out the 1/f noise on a sample-by-sample basis. Theoretically, a chopper op amp therefore has no 1/f noise. luxottica mcdonough human resources

WebThe noise of op-amps is Gaussian with constant spectral density, or “white”, over a wide range of frequencies, but as frequency decreases the spectral density starts to rise at about 3 dB/octave. This low-frequency noise characteristic is known as “1/f noise” since the noise power spectral density goes inversely with frequency (actually 1/f g ). jean tinguely paintingsWebRanges • No Frequency Compensation Required • No Latch-Up 2 Applications • DVD Recorders and Players • Pro Audio Mixers 3 Description The µA741 device is a general-purpose operational amplifier featuring offset-voltage null capability.
