DESCRIPTION
The TL082, TL082A and TL082B are high speed
J–FET input dual operational amplifiers incorpo-
rating well matched, high voltageJ–FET andbipo-
lar transistors in a monolithic integrated circuit.
The devices feature high slew rates, low input bias
and offset current, and low offset voltage temper-
ature coefficient.
