I use your ADuM1400 and ADuM1402 1Mbps and 10Mbps versions. My distributor now
has 2 different types: ADuM1402ARWZ and ADuM1402WSRWZ. Where is the difference
between them? The datasheet just lists A, B and C-grade, depending on frequency.
The ADuM1402WSRWZ and ADuM1402WTRWZ are automotive qualified parts. They have
been tested and approved for automotive applications and have an operating
temperature range of -40C to +125C.
ADuM1402WSRWZ is 1Mbps part and ADuM1402WTRWZ is 10Mbps part.
