The MCP3551-E/SN is a 1-channel 22-bit low-power Analogue-to-digital Converter (ADC). The devices offer output noise as low as 2.5µVrms with a total unadjusted error of less than 10ppm. The family exhibits less than 6ppm integral non-linearity (INL) error, 3µV offset error and 2ppm full scale error. This device 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.
