JFET Input Operational
Amplifiers
These low–cost JFET input operational amplifiers combine two state–of–
the–art linear 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 BIFET 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 products.

NOTES: 1. The magnitude of the input voltage must not exceed the magnitude of the supply voltage or
15 V, whichever is less.
2. The output may be shorted to ground or either supply. Temperature and/or supply voltages
must be limited to ensure that power dissipation ratings are not exceeded.
3. ESD data available upon request.

2. Input Bias currents of JFET input op amps approximately double for every 10°C rise in Junction Temperature as shown in Figure 3. To maintain
junction temperature as close to ambient temperature as possible, pulse techniques must be used during testing.
