Nowadays, many devices operate on smart sensor technology. And because they often use analog output, these devices need an analog-to-digital converter. However, there are not many better options than the MCP3008 pinout.
Unlike the Raspberry Pi, the MCP3008 chip has hardware SPI support that reads analog input. Also, it is affordable compared to other development tools. At the same time, it gives you optimum designs. Going further, you get to learn where to use this logic-level microchip and how to get the best out of it.

Features and Specifications
Below are some features and specs of the mcp3008 pinout.
- Firstly, it is an 8-channel 10-Bit ADC IC.
- Also, its communication protocol is via an SPI interface.
- The operating voltage ranges from 2.7V to 5V.
- On the other hand, the sampling rate for 75 ksps and 200 ksps are 2.7V and 5V, respectively.
- Further, it uses successive approximations as its ADC method.
- In most cases, the standard packages available are the 16-pin PDIP, SOIC, and TSSOP.
- The MCP3008 pinout has programmable analog inputs.
- Also, it has a sample-and-hold feature for on-chip operations.
- The IC runs on CMOS technology and uses low power.
- Further, it uses a standby current of 5nA and a max of 2 µA.

Alternatives ADC ICS
However, there are a couple of alternatives for the MCP3008 IC. They include:
Where to use MCP3008?
Typically, when the IC measures analog voltage value, it sends this value to an MCU via SPI communication. Therefore, you use the MCP3008 pinout with microcontrollers that operate on 3.3V or 5V. Often, these systems include the Raspberry Pi, etc.

How to use the MCP3008 pinout?
First, set the ADC in an optimum operating voltage range of 2.7V - 5V. Note that the reference voltage must never exceed the operating voltage. Otherwise, match the VREF to 5V in line with the VCC pin.
Typically, channel 0 up to channel seven helps supply analog voltage for measurement purposes. As a result, each analog input channel pin gives a 10-bit resolution with the reference voltage and the maximum voltage. In other words, an input voltage ranging between 0V and 5V yields 0-1023 digital data.
After measuring analog voltage, the microprocessor helps you obtain the value via SPI communication. To achieve this, you need to connect the Clock pin, Din, Dout, and CS pin to the SPI pins of the MCU.
