MOTOROLA LF351N Family of jfet operational amplifier Datasheet

Order this document by LF347/D
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.
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.

NOTES: 1. Unless otherwise specified, the absolute maximum negative input voltage is
limited to the negative power supply.
2. Any amplifier output can be shorted to ground indefinitely. However, if more than
one amplifier output is shorted simultaneously, maximum junction temperature
rating may be exceeded.

close to ambient as is possible, pulse techniques are utilized during test.
