JLAF771 SINGLE JLAF772 DUAL JLAF774 QUAD BIFET
OPERATIONAL AMPLIFIER FAMILY
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - These monolithic JFET input operational
amplifiers incorporate well matched ion implanted JFETS on the same chip with standard bipolar transistors. The key features of these op amps are low input bias currents in the sub nanoamp range plus high slew rate (13 V//LS typically) and wide bandwidth (3.0 MHz typically).
LOW INPUT BIAS CURRENT - 200 pA FOR p.AF77X LOW INPUT OFFSET CURRENT - 100 pA FOR p.AF77X HIGH SLEW RATE - 13 V/p.s TYPICALLY WIDE BANDWIDTH - 3.0 MHz TYPICALLY
