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). They provide output noise as low as 2.5 µVRMS and a total unadjusted error of 10 ppm. With a differential input and wide common mode range, these ADCs are well-suited for industrial control, process control, and sensor measurement applications. The MCP3550/1/3 devices operate from -40°C to +125°C and are available in MSOP and SOIC packages.
