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
