ADG428:  Descrepancy between maximum operating temperature in selection tool and web page order guide

In your selection chart the ADG428 is specified to 125°C but in order selection
it is only specified to 85°C
Also, is it possible to use the ADG428 at 150°C at low switch speed ?


The Operating Temperature Range for ADG428 is 40°C to +85°C
We did previously have an Extended Temperature Range (T Version) with a
temperature range of  –55°C to +125°C but the T version is now obsolete. I
apologize because the selection guide needs to be updated to remove the T
version. I have notified our marketing people of this error and this oversight
should be resolved in near future.

The absolute maximum junction temperature of ADG428 is 150°C so you can't use
this device at 150°C even
at low speeds without risk of permanently damaging the device.
