The ADC121C027CIMK is a 12-bit successive-approximation Analogue-to-digital Converter that operates from a +2.7 to 5.5V supply. The low-power monolithic converter is based upon successive approximation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz. This converter operates from a single supply which also serves as the reference. The device features an I2C-compatible serial interface that operates in all three speed modes, including high speed mode 3.4MHz. The ADC121C021's Alert feature provides an interrupt that is activated when the analogue input violates a programmable upper or lower limit value. The device features an automatic conversion mode, which frees up the controller and I2C interface. In this mode, the ADC continuously monitors the analogue input for an "out-of-range" condition and provides an interrupt if the measured voltage goes out-of-range.
