AD549_08 Datasheet, PDF (3/20 Pages) Analog Devices – Ultralow Input Bias Current Operational Amplifier

AD549
SPECIFICATIONS
@ 25°C and VS = ±15 V dc, unless otherwise noted; all minimum and maximum specifications are guaranteed; specifications in boldface
are tested on all production units at final electrical test, and results from those tests are used to calculate outgoing quality levels.
