The Microchip Technology MCP3422A2-E/SN is a high-accuracy, low-noise 18-bit Sigma-Delta Analog-to-Digital Converter (ADC). It features a differential input and an I2C serial interface, supporting standard, fast, and high-speed modes. The device operates from a single 2.7V to 5.5V power supply and is designed for an extended temperature range of -40°C to +125°C.
Key specifications include an 18-bit resolution, a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8, and an on-board voltage reference. The ADC offers programmable data rates up to 240 SPS, with a typical rate of 3.75 SPS at 18-bit resolution. It also includes self-calibration for internal offset and gain per conversion.
This ADC is suitable for applications requiring precise analog measurements, such as portable instrumentation, temperature sensing, and weigh scales. It is available in an 8-SOIC surface-mount package.
