The LM119QML/LM119 is the same device with a military rating.
The LM211/LM111 is a different comparator with a separate output ground.
None of these devices has a TSSOP package.
Part Number: LM111 Hello, Customer is saying they have in their 15-yr old BOM a part marked LM111FK (without the "B"). However, upon checking the part marking tool and material information tool, there seems to be no LM111FK available. (1) May I…
Part Number: LM111
I have the given circuit I made in Proteus software. It is just a basic question regarding the op-amp working. How does the 100k resistor in positive feedback affect the circuit. Why is this necessary?
Hello Heidelberg,
The LM111 is not a rail-to-rail input. The LM111 valid input ranges from 500mV above V- to 1.5V below V+.
So with a ±8V supply, the valid input range would be -7.5 to +6.5V. So the full ±8V signal would violate the input range.…
Part Number: LM111 Can Servo loop implementation be used to determine the Input offset voltage of open collector comparator?
Being a beginner, I tried to simulate the servo loop concept to measure the Vos of LM111. Below is the snap of simulated circuit…
Part Number: LM211-EP Other Parts Discussed in Thread: LM111 Is input offset voltage expected to shift as a device ages during extended storage with conditions within those specified on the datasheet?

Part Number: LM211 Other Parts Discussed in Thread: LM311 , LM111 Hi team,
Could you provide LM211 pspice model?
I tried to download it, but only LM311 model is available.
Looking at EC table, LM211 electric characteristic is different from LM311.
Regards…

Hi team,
Could you please provide the worst case maximum ICC+ value at TA=85degC and VCC=5V (single supply) of LM211?
My customer is trying to update the power supply and estimating the…
Hello Hari,
The application note was written for the LM111, which has very high input bias currents. Because of these currents, the "Rs" needed to be fairly small values. If you are using a 100 ohm Rs, after 510k, the ratio is so large that it may not…
Hello Santhosh,
The models model typical room temp behavior, so as Kai said. the LM311 model is good for the LM111, 211 and 311 family. The model will be worst-case of the bunch (LM311).
