Microchip (MCP3550-50E/SN) Analogue to Digital Converter, Delta Sigma

Analogue to Digital Converter, Delta Sigma, 22 bit, 12.5 SPS, Differential, 3 Wire, Serial, Single Product Overview The MCP3550-50E/SN is a 22-bit 1-channel delta-sigma low-power Analogue-to-Digital Converter offers 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. The MCP355X device provides high accuracy and low noise performance for applications where sensor measurements such as pressure, temperature and humidity are performed. The converter with the internal oscillator and high oversampling rate, minimal external components are required for high accuracy applications. The fully differential analogue inputs make it compatible with a wide variety of sensor and measurement applications.
