MCHPMCP3221A5T-E/OT
Overview
The MCP3221A5T-E/OT is a 12-bit successive approximation register (SAR) Analog-to-Digital Converter that features a single-ended input in a tiny 5-pin SOT-23 package. It communicates via an I2C-compatible serial interface and is designed for applications requiring high-resolution data acquisition with minimal board space and power consumption.
Why Choose This Part
This ADC offers a high resolution-to-size ratio, providing 12-bit precision in a compact SOT-23-5 footprint. Its wide operating voltage range of 2.7V to 5.5V ensures compatibility with both 3.3V and 5V logic systems without additional level shifting.
Applications
Getting Started
Engineers can evaluate this part using a standard I2C bus from any microcontroller like a PIC or Arduino. Ensure a stable reference voltage at VDD as the device uses the supply rail as its voltage reference.
