Q
Would you tell if AD5420/2 are HART compatible now? Some customer willintegrate HART in application. But now they only have AD421 to use. If we may
also promote this part to meet HART compatible now?
A
The AD5420 has passed the HART physical layer tests and is therefore HARTcomplatible. There is an application note on configuring this device to meet
HART communications compliance - AN-1065 : Configuring the AD5420 for HART
