MOTOROLA ANALOG IC DEVICE DATA
JFET Input Operational
Amplifiers
These lowcost JFET input operational amplifiers combine two stateof
theart 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 pincompatible with the industry standard MC1741,
MC1458, and the MC3403/LM324 bipolar products.
Input Offset Voltage Options of 6.0 mV and 15 mV Max
Low Input Bias Current: 30 pA
Low Input Offset Current: 5.0 pA
Wide Gain Bandwidth: 4.0 MHz
High Slew Rate: 13 V/
s
Low Supply Current: 1.4 mA per Amplifier
High Input Impedance: 1012

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.
