BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4084
J-FET INPUT QUAD OPERATIONAL AMPLIFIER
DESCRIPTION
The µPC4084, is a quad operational amplifier incorporating well matched ion implant P-channel J-FET on the same chip
with standard bipolar transistors. The key features of this op amp is very low input bias current and high slew rate ten times
faster than conventional general purpose op amps. By these features µPC4084, is excellent choice for wide variety of
applications including integrator, active filter, pulse amp etc.
FEATURES
• Low noise: en = 25 nV/ Hz (TYP.)
• Very low input bias and offset currents
• Output short circuit protection
• High input impedance...J-FET Input stage
• Internal frequency compensation
• High slew rate...13 V/µs (TYP.)
