MCHPMCP3008
Overview
The MCP3008 is an 8-channel, 10-bit Analog-to-Digital Converter (ADC) that communicates over a standard SPI serial interface. It allows microcontrollers or single-board computers that lack integrated analog inputs to measure up to eight different analog signals with a sampling rate of up to 200 ksps at 5V.
Why Choose This Part
The device features a simple SPI interface that requires only four pins for communication and supports a wide operating voltage range from 2.7V to 5.5V. Its low power consumption, with a typical standby current of only 5 nA, makes it suitable for battery-operated applications requiring occasional sensor polling.
Applications
Getting Started
For rapid prototyping, the MCP3008-I/P in the 16-pin PDIP package is ideal for breadboard use. Engineers can interface it with a Raspberry Pi using the spidev library or with an Arduino using the standard SPI library by connecting the CS, DIN, DOUT, and CLK pins.
