应用功能:Precision, Low PowerBiFET Op Amp The AD548 is a low power, precision monolithic operationalamplifier. It offers both low bias current (10 pA max, warmedup) and low quiescent current (200 mA max) and is fabricatedwith ion-implanted FET and laser wafer trimming technologies.Input bias current is guaranteed over the AD548’s entire common-mode voltage range.
