Choosing a Precision Op Amp? Analog Devices

where ω is the variable, or the function argument, which is 2 π times frequency, fc is the op amp cutoff frequency, Aol is the open-loop gain at DC, and j is the imaginary unit.

6/03/2010 · Basically it uses a high-wattage rheostat, which is like a high-wattage potentiometer, to attenuate the crossed-over high frequency signal only, while providing the same impedance to the crossover so your x-over frequency remains the same.

Frequency Adjustable Bass Crossover Circuit Electronics

If the speaker is not connected to the crossover, or the speaker has been destroyed (open circuit), the LC 'series resonance' without a load behaves as short circuit at the crossover frequency only. The amplifier can easily be destroyed.

Say Farewell to Offset Voltage with a Zero-Drift Op Amp

Version #2 of my active HiFi speakers Back in 1991 I built a set of large, active speakers, using a subtractive phase-linear crossover circuit, with individual power amplifiers for each driver, that used op amps with wrap-around transistors biased into expanded class-A.

How system operating conditions affect CMOS op amp open

op-amps, resistors and capacitors. Filter types and characteristics A filter is a circuit whose transfer function, that is the ratio of its output to its input, depends upon frequency. There are three broad categories of filter which are widely used: Low-pass filters allow any input at a frequency below a characteristic frequency to pass to its output unattenuated or even amplified. High-pass

How system operating conditions affect CMOS op amp open

17/01/2011 · There will be a transfer function that tells you the attenuation (or gain) at each frequency. You can calculate what it would be for a specific frequency by calculating the impedence of each capacitor and replacing them with equivalent resistors and calculating the op-amp gain.

Figure 5. Gain/phase plots of medium-frequency op amps show frequency extremes The external resistors come into play when the op amp is conFigured as an inverting, noninverting, or differential amplifier. When R F = R G, Equation 1 reduces to Aβ = a/2; and the vertical intercept for the amplifier reduces from that of the buffer by 6 dB. Although the vertical intercept has changed, the pole
