Would you tell if AD5420/2 are HART compatible now? Some customer will
integrate HART in application. But now they only have AD421 to use. If we may
also promote this part to meet HART compatible now?


The AD5420 has passed the HART physical layer tests and is therefore HART
complatible.  There is an application note on configuring this device to meet
HART communications compliance - AN-1065 : Configuring the AD5420 for HART
Communication Compliance
