ADC121C027 12-Bit Analog-to-Digital Converter

The ADC121C021 is a low-power, monolithic, 12-bit, analogto-digital converter(ADC) that operates from a +2.7 to 5.5V supply. The converter is based on a successive approximation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz. The ADC121C02.

ADC121C027 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, w
