The AD549 is a monolithic electrometer operational amplifierwith very low input bias current. Input offset voltage and inputoffset voltage drift are laser trimmed for precision performance.The AD549’s ultralow input current is achieved with “Topgate”JFET technology, a process development exclusive to AnalogDevices. This technology allows the fabrication of extremely lowinput current JFETs compatible with a standard junction-isolated bipolar process. The 1015Ω common-mode impedance,a result of the bootstrapped input stage, insures that the inputcurrent is essentially independent of common-mode voltage.

The AD549 is suited for applications requiring very low input current and low input offset voltage. It excels as a preamp for a wide variety of current output transducers such as photodiodes, photo multiplier tubes, or oxygen sensors. The AD549 can also be used as a precision integrator or low droop sample and hold. The AD549 is pin compatible with standard FET and electrom-eter op amps, allowing designers to upgrade the performance of present systems at little additional cost.
