I2C to SPI bridge for AD7176-2

Hi all,

 

I am currently working on a DAQ system where it would be preferable to use an I2C interface for the AD7176-2 (so that it can be treated as a slave on the I2C bus).

 

I have seen several ICs which act as bridges between I2C and SPI (i.e. SC18IS602) however I'm concerned about the compatibility of these with the SPI implementation on the ADC, in particular due to the DOUT pin also behaving as an interrupt when a sample is ready.

 

Does anyone know of a suitable I2C to SPI bridging IC that will work with the given SPI implementation?

 

Thanks in advance,

Tariq.
