FAMILY OF JFET
OPERATIONAL AMPLIFIERS
These low cost JFET input operational amplifiers combine two
state–of–the–art analog technologies on a single monolithic integrated
circuit. Each internally compensated operational amplifier has well matched
high voltage JFET input devices for low input offset voltage. The JFET
technology provides wide bandwidths and fast slew rates with low input bias
currents, input offset currents, and supply currents.
N SUFFIX
PLASTIC PACKAGE
These devices are available in single, dual and quad operational
amplifiers which are pin–compatible with the industry standard MC1741,
MC1458, and the MC3403/LM324 bipolar devices.

For Typical Characteristic Performance Curves, refer to MC34001, 34002, 34004 data sheet.
NOTE: 3. Input bias currents of JFET input op amps approximately double for every 10°C rise in junction temperature. To maintain junction temperatures as
close to ambient as is possible, pulse techniques are utilized during test.
