TL081

TL081 General purpose JFET single operational amplifiers Features ■ Wide common-mode (up to VCC+) and differential voltage range ■ Low input bias and offset current ■ Output short-circuit protection ■ High input impedance JFET input stage ■ Internal frequency compensation ■ Latch-up free operation ■ High slew rate: 16 V/µs (typ) Description The TL081, TL081A and TL081B are high-speed JFET input single operational amplifiers incorporating well matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low input bias and offset currents, and low offset voltage temperature coefficient.
