Hello,
Our customer has been using LM239 at high ambient temperature EE.
Recently Tj(max) specification is changed from 105degC to 85degC in SLCS006U datasheet.
They care about offset(max) value which was 15mV over Full range, it was -25 to 105degC.
But now, offset is 15mV at -25 to 85degC, seems de-graded offset performance very much.
Is this true understanding that “new production lot” device has larger offset than previous device at 85degC?
Or, actually offset performance is same as “previous lot” device but just changed Tj(max) specification on datasheet?
Regards,
Mochizuki
