Other Parts Discussed in Thread: LM211-EP

I would like to know that LM211-EP setting.

I would like to set VCC+/- are +/-5 and Vout connect resister to gnd. Because Vout swing level from gnd to over +3V.

Does it work correctly with those settings?

Hello Kai,

It looks fine.

Just remember that the allowable input voltage range is -3V to +3.8V.

Hello kai,

It is similar to the circuit I'm imagining.

but, my image is that IC power voltage is +/-5V.

Howver, I understood that my setting work correctly.

Thanks, kai.

if output point emitter of out transister.

I will design output circuit that collector of transister connect to VCC+ and emitter connect to resister through gnd.

Does it work correctly?

Hello Yasuyuki,

Just remember that the output is now inverted when running in open emitter mode. Note the output phase below compared to the above. You will need to swap the inputs to get a similar response.
