Description

The MCP3550-50 devices are 2.7V to 5.5V low-power, 22-bit delta-sigma A/D converters. The devices offer output noise as low as 2.5 Vrms with a total unadjusted error of less than 10 ppm. The MCP3550-50 exhibits less than 6 ppm integral non-linearity (INL) error, 3 V offset error, and 2 ppm full scale error. The MCP3550-50 devices provide 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. The fully differential analog inputs make it compatible with a wide variety of sensor and measurement applications. The MCP3550-50devices operate from -40°C to +125°C and are available in the space-saving 8-pin MSOP and SOIC packages.
