In addition, AC signals with a frequency component are constrained by the slew rate and gain bandwidth product. Here, we consider the relationship between the amplitude and frequency, or slew rate. The opamp determines the maximum frequency that can be output. huanggou.vipWebOct 13, 2009 · There is *NO* relation between slew rate and gain-bandwidth product. Of course there is... it's just not an absolute relationship. Slew rate, in an OpAmp, depends on first stage current. This current generally defines first stage transconductance, which critically influences the size of the pole-splitting capacitor (loop compensation). avion 841

WebOperational Amplifier Example No1. Using the formula 20 log (A), we can calculate the bandwidth of the amplifier as: 37 = 20 log (A) therefore, A = anti-log (37 ÷ 20) = 70.8. GBP ÷ A = Bandwidth, therefore, 1,000,000 ÷ 70.8 = 14,124Hz, or 14kHz. Then the bandwidth of the amplifier at a gain of 40dB is given as 14kHz as previously predicted ... Webthe amplifier is less than this value, we say that the amplifier isslew rate limited. If the slew rate is larger than this value, then the output waveform looks like an exponential and we say it is time constant limited. 4) Record your measured value for the full power bandwidth. Compare this value to the small signal bandwidth measured in part ...
