Overview

The MCP3208-CI/P is a 12-bit Analog-to-Digital Converter (ADC) that combines 8 channels with a high-speed SPI serial interface. It utilizes a Successive Approximation Register (SAR) architecture to provide reliable conversions at rates up to 100ksps while maintaining low power consumption of 0.4mA at 5V.

Why Choose This Part

This ADC offers excellent versatility with software-configurable inputs that support both single-ended and pseudo-differential modes. The PDIP-16 package is particularly advantageous for rapid prototyping and through-hole assembly, while the wide 2.7V to 5.5V supply range ensures compatibility with both legacy 5V systems and modern 3.3V logic.

Applications

Multi-Channel Sensor Logging
Ideal for interfacing up to 8 single-ended sensors or 4 differential pairs to microcontrollers with limited analog pins.
Battery-Powered Instrumentation
Leverages a low 0.5uA standby current and 2uA shutdown current for extended operation in portable devices.
Industrial Process Control
Used for monitoring 0V to VDD analog signals in factory automation where 12-bit resolution is required for precision.
Data Acquisition Systems
Serves as a cost-effective front end for PC-based or embedded logging systems requiring simultaneous multi-point monitoring.

Getting Started

To begin evaluation, connect the MCP3208 to a microcontroller using a standard 4-wire SPI bus (CS, CLK, DIN, DOUT) and provide an external voltage reference to the VREF pin. Microchip provides extensive C libraries, and the device is a staple in the Raspberry Pi and Arduino ecosystems for expanding analog input capabilities via breadboard-friendly PDIP footprints.
