Op amp with high slew rate
Did you know?
Websee that the higher slew rate amplifier has a much shorter overall settling time because less time is spent in the op-amp’s slew rate limit. The larger the input step, the more time the op-amp will spend in slew limit. Looking at TI’s op-amp catalog, it is easy to see that high slew rate devices are usually high bandwidth devices. Web(30 marks) (b) Now assume it is a non-ideal op-amp with input bias current I BIAS = 1 uA and input offset current I 10 = 0. Calculate the value of v 0 due to the input currents when v i 1 = v i 2 = 0. (30 marks) (c) Now assume that the op-amp has limited slew rate and assume a sinewave is applied to vi1 while vi2 = 0.
Web20 de dez. de 2024 · The LME49720 has no specification of 1MHz PSRR, but at 100kHz it is ~54dB which suggests 34dB PSRR at ~ 1MHz. The LM6172 has ~ 50dB PSRR at 1MHz. The LME49720 has ~ 1.3uV output noise in the actual circuit in the D10S, the LM6172 2.1uV output noise, relative to 2V signal levels, so ~124dB to ~120dB SNR. http://www.learningaboutelectronics.com/Articles/Op-amp-specifications-slew-rate
Web24 de fev. de 2024 · A composite amplifier to raise the SR of the 741 op-amp. With reference to Figure 3 (a), we find it instructive that OA1 has to amplify only by 0 dB, whereas the amplification by 10 V/V is done by the CFA. Smaller output voltage swings by OA1 ought to ameliorate the slew-rate (SR) considerably. Figure 3. Plots for the PSpice circuit of …
