m Quad Low Power Operational Amplifiers
et4U.cohe PJ324 series are low-cost , quad operational amplifiers
T ewith true differential inputs. These have several distinct
hadvantage over standard operational amplifier types in single
taSsupply applications. The quad amplifiers can operate at supply
avoltages as low as 3.0V or as high as 32V with very low
w.DFEATURES
ww• Short circuited protected outputs
quiescent currents and eliminat the necessity for external
biasing components in many
applications. The output voltage range also includes the
negative power supply voltage.

SOP -14
• True differential input stage
• Single supply operation:3.0V to 32V
m• Low input bias currents:100nA Max
o• Four amplifiers per package
.c• Internally compensated
U• Common mode range extends to negative supply
t4• Industry standard pinouts
• ESD clamps on the inputs increase raggedness without
eaffecting device operation
