LF411C
LF412C
Low Offset, Low Drift JFET
Input Operational Amplifiers
Through innovative design concepts and precision matching this
monolithic high speed JFET input operational amplifier family offers very low
input offset voltage as well as low temperature coefficient of input offset
voltage. The amplifier requires less than 3.4 mA per amplifier of supply
current yet exhibits greater than 2.7 MHz of gain bandwidth product and
more than 8.0 V/µs slew rate. Through the use of JFET inputs the amplifier
has very low input bias currents and low input offset currents. The amplifier
utilizes industry standard pinouts which afford the user the opportunity to
directly upgrade circuit performance without the need for redesign.
The LF411C and LF412C are available in the industry standard plastic
8–pin DIP and SO–8 surface mount packages, and specified over the
commercial temperature range.
