ADC0804-N: Can't find an ADC with free-running feature as in ADC0804

Part Number: ADC0804-N
Other Parts Discussed in Thread: ADS1018

Hello,

actually, the question is not exactly about the ADC0804 but rather about finding an ADC that fits my design and has a certain feature like this ADC. The feature is the free-running option (like implemented on page 42 in the datasheet).

To be more specific I'll tell exactly what I am looking for and couldn't find.

I need an SMT ADC, I don't need more than 1 channel (I don't care if it has more, I just won't use them). I need the output will be one serial port (unlike ADC0804 that is parallel) and I want it to be small as possible (I'd like to find around 10 mm^2 but if there isn't one so I'd like to find the smallest possible component).

I hope someone can help me. I'm really stuck.

P.S.: If someone has an idea of how to externally add a feature like this to any ADC with SPI interface, for example, I'll be glad to hear.
