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. These ADCs are ideal for applications requiring high accuracy and low noise performance, such as weigh scales, direct temperature measurement, instrumentation, data acquisition, and strain gauge measurement. The devices operate from -40°C to +125°C and are available in MSOP and SOIC packages.
