Texas Instruments TL343

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 30 v. operation from split supplies also is possible provided the difference between the two supplies is 3 v to 30 v. the common-mode input range includes the negative supply. output range is from the negative supply to vcc 1.5 v.
