JFET Input 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 BIFET
technology provides wide bandwidths and fast slew rates with low input bias
currents, input offset currents, and supply currents.
The ON Semiconductor BIFET family offers single, dual and quad
operational amplifiers which are pin–compatible with the industry standard
MC1741, MC1458, and the MC3403/LM324 bipolar devices. The MC34001/
34002/34004 series are specified from 0° to +70°C.

3. The input bias currents approximately double for every 10°C rise in junction temperature, T
J
. Due to limited test time, the input bias currents are
correlated to junction temperature. Use of a heatsink is recommended if input bias current is to be kept to a minimum.
4. Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously, in accordance with common practice.
