Fonctionnalités et applications

The MCP3551-E/SN is a single Channel 2.7 V 22-Bit Delta Sigma A/D Converter available in Surface Mount SOIC-8 Package.

It provides high accuracy and low noise performance for applications where sensor measurements (such as pressure, temperature and humidity) are performed. With the internal oscillator and high oversampling rate, minimal external components are required for high-accuracy applications.
