Overview
The ADC101C021 is a low-power, monolithic, 10-bit analog-to-digital converter (ADC) produced by Texas Instruments. It operates from a single supply voltage ranging from +2.7V to +5.5V, which also serves as the reference voltage. The converter is based on a successive approximation register architecture with an internal track-and-hold circuit capable of handling input frequencies up to 11MHz. This ADC is designed for low power consumption and is available in small packages, making it an excellent choice for battery-operated equipment and other applications requiring minimal power usage.
