AD549KH/+ +BOM

High-performance operational amplifier for precision applicatio

AD549KH/+ Descrizione generale

Elevate your precision amplification needs with the AD549KH electrometer operational amplifier from Analog Devices, Inc. Crafted with laser-trimmed input offset voltage and drift, this monolithic amplifier guarantees unparalleled accuracy and stability in low input current applications. The Topgate™ JFET technology unique to the AD549KH enables ultralow input currents, making it a standout choice for applications requiring precision amplification. Its bootstrapped input stage delivers a 1015 Ω common-mode impedance, ensuring consistent input current regardless of common-mode voltage fluctuations. Whether used as a preamp for current output transducers or in precision integrators, the AD549KH excels in environments where reliability is key. Encased in a TO-99 hermetic package and offering pin compatibility with standard op amps, this amplifier provides an easy and cost-effective solution for upgrading existing systems. With a maximum quiescent supply current of 700 μA and impressive AC specifications, including a 1 MHz unity gain bandwidth and 3 V/μs slew rate, the AD549KH is a comprehensive amplifier for a variety of demanding applications
