Overview

The MCP3008T-E/SL is an automotive-grade, 10-bit Successive Approximation Register (SAR) analog-to-digital converter featuring an 8-channel multiplexer and an SPI serial interface. It operates with a sampling rate of up to 200ksps and supports both single-ended and pseudo-differential input configurations. This device is widely used to add analog input capabilities to digital-only platforms such as the Raspberry Pi.

Why Choose This Part

The MCP3008T-E/SL offers a high channel count for its small SOIC footprint, allowing for dense analog signal processing. Its SPI interface simplifies communication with microcontrollers and application processors using only four wires. The automotive-grade rating ensures stable performance across a wide temperature range and in harsh electrical environments.

Applications

Automotive Sensor Interfacing
Monitoring various 5V or lower analog sensors in vehicle subsystems requiring AEC-Q100 grade reliability.
SBC Analog Expansion
Adding multiple high-resolution analog input channels to single-board computers like the Raspberry Pi via the SPI bus.
Industrial Data Acquisition
Collecting data from up to eight single-ended sensors for environmental monitoring or process control.
Battery Voltage Monitoring
Utilizing pseudo-differential inputs to monitor battery cell voltages while minimizing common-mode noise.

Getting Started

Connect the MCP3008 to your controller's SPI bus (MISO, MOSI, SCLK, and CS) and provide a stable external reference voltage to the VREF pin. For Raspberry Pi users, the spidev library or the GPIO Zero library provides immediate high-level access to the ADC channels. Ensure that the input voltage does not exceed the VREF or VDD levels to avoid clipping or damage.
