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.

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.
