MCHPMCP3208-CI/SL
Overview
The MCP3208-CI/SL is a 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter featuring 8 input channels. It operates over a wide voltage range of 2.7V to 5.5V and communicates via a standard SPI serial interface. This ADC is particularly suited for applications requiring multiple sensor inputs in a compact 16-SOIC package.
Why Choose This Part
The device offers a high-density 8-channel multiplexer while maintaining a low typical current consumption of 0.4mA at 5V. Its pseudo-differential input capability allows for common-mode rejection, and the external reference input provides flexibility for precision scaling. The 12-bit resolution and SAR architecture deliver reliable performance for general-purpose analog sensing.
Applications
Key Specifications
Getting Started
To begin development, connect the SPI pins (CS, CLK, DIN, DOUT) to your microcontroller and provide a stable external voltage reference to the VREF pin. Microchip provides the MCP3208 Library for the Arduino IDE and MPLAB X XC8 compilers to simplify register configuration. Ensure adequate decoupling capacitors are placed near the VDD pin to maintain 12-bit accuracy during conversions.
