I want to report a bug of max4206 spice model. I downloated the lib file from analog website.
based on datasheet. if Rset is 5M ohm, the Iref should be 10nA, not 100nA. and when Ilog is 10nA, the VLOG1 should be 0V.
However, I found out when I set Rset to 5M ohm, the Iref is set to 100nA in spice mod. Maybe forget to add the 10.
Hello zyfh ,
Your reported bug is acknowledged. I tried using the typical operating circuit on the DS and I also got 100nA and 100uA Iref on 5Mohm to 5kohm Rset resistors.
We will forward this query to the LT Spice forum to properly address your concern.
Thanks and Best Regards,
Kenneth
