TEXAS INSTRUMENTS ADC101C021CIMK/NOPB

The ADC101C021CIMK/NOPB is a 10-bit successive-approximation Analogue-to-digital Converter operates from a +2.7 to 5.5V supply. The low-power monolithic converter is based on successive approximation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz. The ADC101C021 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 ADC'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.
