I've been looking at fast dual ADC chips, with a possible SDR application for the I/Q channels. Most audio codecs run out of gas above 192KSPS (if you want to stick with the data sheet anyway) but there are a number of dual 16-bit ADC's that are specified up to 2MSPS (and beyond), like the MAX1198. However. It appears that dual ADC's like this don't use the I2S interface, but some variant of SPI. For instance, the MAX1198 uses a SPI interface that has one clock and TWO data channels. My question: does Teensyduino support that?? There's nothing to suggest it can, based on what I've seen in the online SPI library docs.

Thanks
