5V Analog Input Over SPI
Hi. I'm working a project that read a sensor value from adc. But sensor supply voltage 8-12VDC and output is 0.5-4.5VDC. I know that LPC1768 ADC input can read to 3.3VDC. For that reason i want to connect sensor output to MCP3201 ADC IC and communicate with SPI. Or simple voltage divider circuit. What is your offers?
Hi Bora,
Thanks for your question, can you clarify a couple of things:

Probably the best way to do this if the scale is linear is to use a voltage divider :)
