Does anyone know of a ADC that meets below specs?

* Daisy-chainable
* SPI
* 8 bit
* >= 100 ks/S
* 8 channels
* Single-ended
* Cost less than $5
 

1) What is a "daisy-chainable" ADC? If you're using SPI, all the devices can share the bus, with discrete select lines.
2) Look at Microchip MC3008. It's about $2 in single pieces.
 

You asked for an SPI device and then show a non-SPI implementation. As I suggested, using an SPI device would accomplish pretty much what you're showing.

I'm not sure what you are referring to but the example I gave you is supporting SPI and daisy chain. The part you showed me, which i'm familiar with, the mcp3008 is not daisy-chainable.
