LM567CM - Absolute Maximum Ratings - Input Voltage

Sven Maier

Other Parts Discussed in Thread: LM567C, LMC567

Hi,

Could you please also check if the datasheet needs to be corrected under section 7.1 Absolute Maximum Ratings. Looks like the 2V needs to move from column MIN to MAX. Can you confirm this?

Best regards,

Sven

The latest revision (E) of the LM567C datasheet has no section 7.1, and no absolute maximum rating of 2 V.

Hi Sven,

Are you referring to LMC567 data sheet instead of LM567C?
If that's the case I think that 2Vp-p should be moved to MAX.

Hi Ivan,

thanks a lot. Yes I'm referring to LMC567. So this could be the answer for causing troubles when moving from LM567C (with up to 9V input) to LMC567 (max 2V).

Could you please also check section 7.2. The given unit behind the input frequency (Fin) is Hz. Are you sure this shouldn't be kHz?

Regards,

Sven

Sven,

It seems that this is another typo. Other sections of the same document specify that LMC567 operates at input frequencies from 1Hz to 500kHz.
Unit in section 7.2 shouldn't be changed to kHz as this could imply that MIN is 1kHz. However this should be fixed.
