Frequently Asked Questions
How many analog input channels does MCP3008-I/P offer, and in which input configurations?
The MCP3008-I/P provides 8 single-ended input channels or 4 pseudo-differential input pairs, all multiplexed to a single 10-bit successive-approximation ADC, giving designers flexible measurement configurations for up to 8 independent sensors on a single chip.
What is the maximum sample rate and conversion time of MCP3008-I/P in a 5 V system?
At 5 V supply, the MCP3008-I/P achieves a maximum sample rate of 200 ksps with a conversion time of 2.7778 µs per channel, making it suitable for audio, vibration monitoring, and multi-channel industrial process control applications requiring timely analog updates.
How does MCP3008-I/P connect to a Raspberry Pi or other 3.3 V SPI host?
The MCP3008-I/P operates at 2.7 V to 5.5 V, so a 3.3 V Raspberry Pi can drive it directly via SPI CS, CLK, MOSI, and MISO lines without level shifting, enabling acquisition of up to 8 analog channels at 75 ksps on the 3.3 V rail.
For a 16-channel analog front-end design, how many MCP3008 devices are needed?
Two MCP3008-I/P devices provide 16 single-ended channels; each uses a separate SPI chip-select line while sharing the same CLK and MISO/MOSI bus, requiring only 6 microcontroller pins total and minimal additional PCB space.
