AD549 Datasheet (Analog Devices) - Ultralow Input Bias Current Operational Amplifier

AD549, Ultralow Input Bias Current Operational Amplifier

The AD549 is a monolithic electrometer operational amplifier with very low input bias current.

Input offset voltage and input offset voltage drift are laser trimmed for precision performance.

The ultralow input current of the part is achieved with Topgate™ JFET technology, a process development excl
