TL081 Wide Bandwidth JFET
Input Operational Amplifier
General Description
The TL081 is a low cost high speed JFET input operational
amplifier with an internally trimmed input offset voltage
(BI-FET IITM technology) The device requires a low supply
current and yet maintains a large gain bandwidth product
and a fast slew rate In addition well matched high voltage
JFET input devices providevery low input bias and offset
currents The TL081 is pin compatible with the standard
LM741 and uses the same offset voltage adjustment circuitry This feature allows designers to immediately upgrade the
overall performance of existing LM741 designs
The TL081 may be used in applications such as high speed
integrators fast D A converters sample-and-hold circuits
and many other circuitsrequiring low input offset voltage
low input bias current high input impedance high slew rate
and wide bandwidth The devices has low noise and offset
voltage drift but for applications where these requirements

are critical the LF356 is recommended If maximum supply
current is important however the TL081C is the better
choice
