ADC121C027CIMK

TEXAS INSTRUMENTS  ADC121C027CIMK  模数转换器, 12 bit, 188.9 kSPS, 单, 2.7 V, 5.5 V, TSOT

The 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.

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
