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

current and yet maintains a large gain bandwidth product

and a fast slew rate In addition well matched high voltage

JFET input devices provide very low input bias and offset

currents The TL081 is pin compatible with the standard

LM741 and uses the same offset voltage adjustment circuit-

ry 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 DA converters sample-and-hold circuits

and many other circuits requiring 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
