Product Summary

The AD549LHZ is a ultralow input bias current operational amplifier. The application of the AD549LHZ are: Electrometer amplifier; Photodiode preamp; pH electrode buffer; Vacuum ion gauge measurement. The AD549LHZ 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 exclusive to Analog Devices, Inc. This technology allows 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.
