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.

• Input Offset Voltage of 5.0 mV Max (LF347B)

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.
