The Microchip Technology Inc. MCP3550/1/3 devices are 2.7V to 5.5V low-power, 22-bit Delta-Sigma Analog-to-Digital Converters (ADCs). These ADCs provide output noise as low as 2.5 µVRMS and a total unadjusted error of 10 ppm, making them ideal for applications requiring high accuracy and low noise performance, such as weigh scales, direct temperature measurement, and data acquisition systems. The devices operate from -40°C to +125°C and are available in MSOP and SOIC packages.
