AD503KH high-performance, legacy operational amplifier (NOS)

The AD503KH is a high-performance, legacy operational amplifier designed for precision analog circuits. Encased in a hermetic CAN-8 metal package, it offers exceptionally low input bias current—typically in the picoampere range—thanks to its JFET input stage. This op-amp excels in applications demanding low noise and high input impedance, making it ideal for sensitive measurement and instrumentation tasks where stability and accuracy across varying conditions are critical. Its robust packaging also ensures reliable operation in challenging environments.
