XR-084
Quad Bipolar JFET Operational Amplifier
GENERAL DESCRIPTION
The XR-084 quad bipolar JFET operational amplifier is
designed to offer higher performance than convention-
al bipolar quad op amps. Each of the four op amps on
the chip is closely matched in performance character-
istics, and each amplifier features high slew rate, low
input bias and offset currents, and low offset voltage
drift with temperature. The XR-084 JFET input quad op
amp is fabricated using ion-implanted bipolar JFET
technology which combines well-matched JFETs and
high-performance bipolar transistors on the same mon-
olithic integrated circuit.

SYSTEM DESCRIPTION
The XR-084 is a quad JFET input operational amplifier
featuring extremely high input resistance, low input bi-
as and offset currents, large common mode Yoltage
range, and large output swing range. Unity gain band-
width is 3 MHz and slew rate is 13V/p,S. The devices are
unity gain compensated.

Nota 1: For Supply Voltage less than ± 15V, the absolute maximum input voltage is equal to the supply voltage.
Nota 2: 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.
