Eason, I see now. There are two pin-outs because one is for single op-amp TLE2021MD and the other is for dual op-amp TLE2022MD The top one is for TLE2021MD.
Adam,
When there is a failure, is the output always too positive (less negative)? That would suggest the same pin fails in the same way.
Normally I'd think that pin 2 is damaged because that point is common to both amplifiers. However the error voltage…
Other Parts Discussed in Thread: LM741 , UA741 Hi,
I am component engineer working with Honeywell Aerospace.
We are looking for FFF alternate suggestion for discontinued Harris Semiconductor MPN CA3010.
Kindly review and confirm if you have any alternate…
Other Parts Discussed in Thread: UA741 , TLV2470 , TLE2426 Hello all,
I'm designing a DC power supply and am currently prototyping with a UA741 op amp. I put together a variable voltage follower circuit, with the op amp, in hopes of creating constant voltage…
Other Parts Discussed in Thread: UA741 Hi...
This is Surender. I am using UA741 Op amp in our pmu application. Even-though the i/p is ZERO I am getting i/p offset voltage and o/p as 1.81V and 1.81V respectively. I applied different voltages at the i/p…

Respected Sir
I am a MTech student. I read your presentation on noise measurement. I am doing similar kind of noise measurement. My task is to measure 1/f noise of various opamps. So I started with uA741 opamp. I followed your steps…
Other Parts Discussed in Thread: UA741 Hi,
I am performing some basic tests to the uA741 op-amp and I tried to do the continuity test to check for protection diodes, but my results showed that there is no protection.
Would you please tell me if this particular…
Thomas,
When the LM675 is putting out 6.3 Vrms into a 1 ohm resistor we need almost 40 Watts across that resistor which overheats both the 5W resistor and the LM675 supplying its voltage.

Itoh-san,
LM741 is similar schematic but different process. Nevertheless the uA741 noise should be close to what should be expected from LM741.
On these very old designs, the thermal noise is predictable (40nV/root Hz) and the 1/f noise can vary device…
