LOW NOISE QUAD J-FET
OPERATIONAL AMPLIFIER
DESCRIPTION
The UTC TL084 is a high speed J-FET input quad operational
amplifier. It incorporates well matched, high voltage J-FET and
bipolar transistors on a monolithic integrated circuit. The device
features high slew rates, low input bias and offset current, and
low offset voltage temperature coefficient.
FEATURES
*Low power consumption
*Wide common-mode (up to VCC+) and differential voltage range
*Low input bias and offset current
*Low noise eN = 15 (typ)
*Output short-circuit protection
*High input impedance J-FET input stage
*Low harmonic distortion: 0.01%(typ)
*Internal frequency compensation
*Latch up free operation

Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the
supply voltages where the zero reference level is the midpoint between VCC- and VCC+.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts,
whichever is less.
Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be
limited to ensure that the dissipation rating is not exceeded.
