MCP3008 - 8-Channel 10-Bit ADC With SPI Interface

Description: Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required.

This chip is useful for situations needing 8 analog inputs that don't need to be very fast, especially for Linux computers that don't have analog inputs. This is the cheapest way to add 8 analog inputs and because it's SPI, you only need 4 wires. And, you get good, quality readings. And it's through-hole which is super great for quick prototyping!

We have a tutorial and code example for wiring this chip to a Raspberry Pi
