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 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.

  • Wide Range of Supply Voltages, Single Supply 3 V to 30 V, or Dual Supplies
  • Class AB Output Stage
  • True Differential-Input Stage
  • Low Input Bias Current
  • Internal Frequency Compensation
  • Short-Circuit Protection
