Fairchild UAF774
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

NOTES:
1. Rating applies to ambienllemperatures up to 70°C above TA = 70°C. Derate linearly 6.3 mW/"C forthe metal can, 5.6 mWIOClorthe mini DIPand 8.3 mW/"C
lor the DIP.
2. Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
3. 18 and los are measured at VCM = O.•
4. The input bias currents are junction leakage currents which approximately double for every 10°C imease in the junction temperature, Tj. Due to limited
production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the
ambienttemperature as a result 01 internal power dissipation, PD' Tj = TA = ajA PD where ajA is the thermal resistance from junction to ambient. Use of a
heat sink is recommended if input bias current is to be kept to a minimum.
5. Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice.
