The Microchip MCP3424 is a low-noise, high-accuracy 18-bit delta-sigma analog-to-digital (ΔΣ A/D) converter designed for portable instrumentation, consumer goods, temperature sensing, and weigh scales. It offers four differential input channels, an on-board 2.048V reference voltage, and a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8. The device supports one-shot and continuous conversion modes, and operates from a single 2.7V to 5.5V power supply. Its I²C interface allows for flexible configuration and communication, making it suitable for a wide range of industrial applications.
