ADC121C021CIMK/NOPB

АЦП, 12 бит, 188.9 Квыборок/с, Однополярный, 2.7 В, 5.5 В, TSOT-23.

The ADC121C021CIMK/NOPB is a 12-bit monolithic Analog-to-digital Converter (ADC) that operates from a 2.7 to 5.5V supply. The low-power 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 I?C-compatible serial interface that operates in all three speed modes, including high speed mode. The 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 I?C 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-of-range. The automatic power-down feature reduces the power consumption to less than 1µW while not converting.
