D Internal Frequency Compensation D Short-Circuit Protection description/ordering information 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.

2 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 V. ORDERING INFORMATION. VIOMAX ORDERABLE TOP-SIDE. TA PACKAGE . AT 25 C PART NUMBER MARKING .

5 Differential voltages are at IN+ with respect to IN . 3. Neither input must ever be more positive than VCC+ or more negative than VCC . 4. Maximum power dissipation is a function of TJ(max), JA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) TA)/ JA. Selecting the maximum of 150 C can affect reliability. 5. The package thermal impedance is calculated in accordance with JESD 51-7. 2 POST OFFICE BOX 655303 DALLAS, TEXAS 75265..
