AD549 Ultra Low Input Bias Current Operational Amplifier – TO-8 Package
The AD549 is a monolithic electrometer operational amplifier with a 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 exclusive to Analog Devices, Inc. This technology allows the fabrication of extremely low input current JFETs compatible with a standard junction-isolated bipolar process. The 1015 Ω common-mode impedance, which results from the bootstrapped input stage, ensures that the input current is essentially independent of the common mode voltage.
