Description
The ADC121C021 is a low-power, monolithic, 12-bit, analogto-digital converter(ADC) that operates from a +2.7 to 5.5V supply..
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 analog 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 analog input for an "out-of-range" condition and provides an interrupt if the measured voltage goes out-.
