Well...Hi,
when I see such questions .. I ask myself: why did you chose this part?
What I mean: with my applications, I first decide my requirements .. then look for devices that meet my requirements.
Thus If I need a device with SPI interface .. I just do it using their selection guide .. and never would get a non_SPI recommendation.

From the DS, the MAX11254 chip has a proper SPI implementation so it is not compatible here.you can look at an arduino library for this chip to figure out how it works.

Farnell lists 100+ ADCs with I2C interface and 14+ bits resolution.Upon inquiring with all possibly supplier we have, there is nothing out there except this chip and one
Klaus, just because you can see stuff on Farnell, does not mean I can design it into a circuit here.Hi,
Farnell lists 100+ ADCs with I2C interface and 14+ bits resolution.
Usully there are even more with SPI interface....
Cheap, small, multiple channels ... everything is available. But you find only one ... an this is an expensive one without standard interface.
I wonder..
Klaus
What are your actual design constrains? So far we only know/assume you need
Questions
- 5 ADCs
- 16 Bit resolution (?)
- I²C interface (even SPI is not usable as you only have 2 spare pins; except by using a multi channel ADC)

- what are your space limitations?
- price target?
- Required data update rate?
- minimum ADC sample rate?
- actual required resolution?
It´s not meant condescending .. I just use the informations you gave. This is ADC, I2C, cost .. you gave not much more. And with this - your - informations I did a part search. And found 100+ .. on one single distributor.You come across quite condescending often in you replies
The IC you looked at sends digital data. What's to stop you from finding its output on one or other line?compatible with "with the 2-wire interface"
I designed this into my circuit and another prototype flavour PCB today.What are you multiplexing? The digital interface or the analog inputs? Based on the informations in post #5, I would assume the digital interface.
Have a look on the AD7689 it hosts 8 ADCs in as single package, is cheaper than 5 pcs of MAX11205 and has a 4 wire interface (-> I²C + 2 Spare pins). Size wise it comes in a LFCSP package with 4 mm x 4 mm.
