Overview
The ADC101C021CIMM/NOPB from Texas Instruments is a low-power, monolithic, 10-bit analog-to-digital converter (ADC) designed for a wide range of applications. It operates from a single supply voltage of +2.7 to +5.5V, which also serves as the reference voltage. The ADC is based on a successive approximation register architecture with an internal track-and-hold circuit capable of handling input frequencies up to 11MHz. This device features an I2C-compatible serial interface that supports standard, fast, and high-speed modes up to 3.4MHz. The ADC101C021 is particularly suited for battery-operated equipment due to its low power consumption and compact packaging options.
