EXAR XR-082
XR-082/083
Dual Bipolar JFET Operational Amplifier
GENERAL DESCRIPTION
The XR-082/XR-083 family of dual bipolar JFET opera-
tional amplifiers are designed to offer higher perform-
ance than conventional bipolar op amps. Each amplifier
features high slew rate, low input bias and offset cur-
rents, and low offset voltage drift with temperature.
These operational amplifier circuits are fabricated us-
ing ion-implantation technology which combines well-
matched junction JFETs and high-performance bipolar
transistors on the same monolithic chip.
The XR-082 of family of dual bipolar JFET op amps are
packaged in 8-pin dual-in-line packages. The XR-083
family of op amps offer independent offset adjustment
for each of the individual op amps on the same chip,
and are available in 14-pin dual-in-line packages.

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