Overview

The MCP3208-CI/SL is a 12-bit Analog-to-Digital Converter (ADC) that combines high performance with low power consumption in a compact 16-pin SOIC package. It features an 8-channel multiplexer that can be configured for single-ended or pseudo-differential inputs, making it highly versatile for multi-sensor systems. Communication is handled via a standard SPI serial interface, compatible with most microcontrollers and single-board computers.

Why Choose This Part

This ADC offers a high level of integration with its internal 8-channel MUX, reducing the need for external switching components. The wide operating voltage range of 2.7V to 5.5V ensures compatibility with both legacy 5V systems and modern low-power 3.3V logic. Its Successive Approximation Register (SAR) architecture provides a balanced ratio of speed and precision for general-purpose embedded applications.

Applications

Sensor Interface
Converting analog signals from up to eight different sensors like thermistors, light sensors, or strain gauges into digital data.
Battery Operated Systems
Utilizing the low 2uA standby current and 0.32mA to 0.4mA active current to extend battery life in portable electronics.
Process Control
Monitoring voltage levels in industrial automation loops where 12-bit SAR architecture provides reliable, high-resolution feedback.
Data Acquisition
Gathering multi-channel analog data at sample rates up to 100ksps for logging or real-time analysis.

Getting Started

To interface with the MCP3208, connect the SPI lines (CS/SHDN, DIN, DOUT, CLK) to your microcontroller and provide an external voltage reference to the VREF pin. Ensure proper decoupling of the VDD pin with a ceramic capacitor placed close to the device. For prototyping, this SOIC package can be used with a 150-mil SOIC-16 to DIP adapter on a breadboard.
