description

The TL343 is a single operational amplifier similar in performance to the µA741, 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

– 1.5 V.

CC

The TL343 is characterized for operation from –40°C to 125°C.
