PRODUCT DESCRIPTION
The AD548 is a low power, precision monolithic operational amplifier. It offers both low bias current (10 pA max, warmed up) and low quiescent current (200 µA max) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD548’s entire common-mode voltage range.
