I'm trying to find a way to read 4 analog signals simultaneously. The only interface available from the MCU is an SPI bus (as in CLK, MISO, MOSI, and CS).
The analog signals are 0 to 5V. I need 8-bit resolution or better. Speed is not a concern.
I've been searching through all kinds of ADCs but havn't found anything suitable. I'm open to using some kind of converter or even a second MCU between the ADC(s) and SPI to get it working.
Does anybody have any ideas?
