I'd like to know the Absolute Maximum Rating for SLEEP pin of REF195. Is it the same as Vs which is -0.3V to +18V ?
Hi Hiroyuki-san,I moved your question to its proper community Voltage References.Regards,Goz
After analyzing REF195 schematic, there are ESD diodes connected to sleep pin as voltage clamps. The absolute maximum rating of REF195 sleep pin is -0.3V to VS+0.3.
