LM293: input common voltage range as a function of temperature

Part Number: LM293
Other Parts Discussed in Thread: LMV393

Hello,

I'am using LM293DGK on my design supplied with a 3V3. 

I would like to know if you can send me a curve of the common mode input voltage range as a function of temperature?

(in fact it is written Vcc-2V max at 85°C but how it varies depending the temperature?)

What comparator could i use with the same pinout with higher Vcm, LMV393 possible but specified at 5V not 3V3....

Thanks for your support.

regards

    Hi Cedric,

    Unfortunately we do not have a curve for how the common mode input voltage range varies as a function of temperature. The part however will have a maximum input common mode voltage of Vcc-2V over the temperature range of -25°C to 85°C.  You can take a look at devices like the TLV3702, TLV1702, TLV3402, and LMC6772 for a larger input common mode range. If you need a faster device, the TLV3202 can also be an option.

    Regards,
