Overview
The ADC081C027CIMK/NOPB is a low-power, 8-bit analog-to-digital converter (ADC) produced by Texas Instruments. This monolithic ADC operates from a single supply voltage ranging from 2.7V to 5.5V and is based on a successive approximation register (SAR) architecture. It features an internal track-and-hold circuit capable of handling input frequencies up to 11MHz. The device is designed for use in battery-operated equipment due to its low power consumption and small package size.
