应用功能:Ultralow Noise,High Speed, BiFET Op Amp The AD745 is an ultralow noise, high speed, FET inputoperationalamplifier.Itoffersboththeultralowvoltage noiseand high speed generally associatedwithbipolar input op ampsand the very low input currents of FET input devices. Its 20MHz bandwidth and 12.5 V/ms slew rate makes the AD745 andeal amplifier for high speed applications demanding low noiseand high dc precision. Furthermore, the AD745 does notexhibit an output phase reversal.
