description
The TL343 is a single operational amplifier similar in performance to the
A741, but with several distinct
advantages. It is designed to operate from a single supply over a range of voltages from 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. The
common-mode input range includes the negative supply. Output range is from the negative supply to
V
CC
1.5 V.
The TL343 is characterized for operation from 40
C to 125
C.

All characteristics are measured under open-loop conditions with zero common-mode voltage unless otherwise specified. Full range for TA is
40
C to 125
C.
The VICR limits are linked directly, volt-for-volt, to supply voltage; the positive limit is 2 V less than VCC+.
Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.
NOTE 5: VIO, IIO, IIB, and ICC are defined at VO = 0.
