Just got an E-Mail from Analog Devices. My 2 samples are due to be
delivered here on 6 Feb. It looks like from the specs that the ADuM1251
should work. But, the Si570 requires a lower low(.5V max) than the I2C
spec (.3 X Vcc or .99V for 3.3V). I'm sure we would make Art very happy
if we both use the same chip!
