description
The TL092 JFET-input operational amplifier is similar in performance to the MC3403 family, but with much
higher input impedance derived from a FET input stage. The N-channel-JFET input stage allows a
common-mode input voltage range that includes the negative supply voltage and offers a typical input
12
impedance of 10
Ωꢀ a typical input offset current of50 pA, and a typical input bias current of 200 pA. This device
is designed to operate from a single supply over a range of 3 V to 36 V. Operation from split supplies also is
possible, provided the difference between the two supplies is 3 V to 36 V. Output voltage range is from V
CC−
to V
− 1.3 V, with a load resistor to V
.

The TL092 is characterized for operation from 0°C to 70°C.
