Overview
The ADC101C021CIMK/NOPB is a low-power, monolithic, 10-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device operates from a single supply voltage ranging from +2.7V to +5.5V and is based on a successive approximation register architecture with an internal track-and-hold circuit. It can handle input frequencies up to 11MHz and features an I2C-compatible serial interface that supports standard, fast, and high-speed modes up to 3.4MHz. The ADC is designed for low power consumption and is available in small SOT-6 and VSSOP-8 packages, making it an excellent choice for battery-operated equipment.
