TL084, TL084A, TL084B
General purpose JFET quad operational amplifiers
Datasheet — production data
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 (typical)
Description
The TL084, TL084A, and TL084B are high-speed,
JFET input, quad 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.
