TL081 Wide Bandwidth JFET Input Operational Amplifier
December 1995
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 Provide Very 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 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
Typical Connection
Are Critical The Lf356 Is Recommended If Maximum Supply Current Is Important However The Tl081c Is
the better choice
