Overview
The ADC082S021CIMM/NOPB is a low-power, two-channel CMOS 8-bit analog-to-digital converter (ADC) produced by Texas Instruments. This converter is distinguished by its high-speed serial interface and is fully specified over a sample rate range of 50 ksps to 200 ksps. It employs a successive-approximation register architecture with an internal track-and-hold circuit, allowing it to accept one or two input signals at inputs IN1 and IN2. The ADC082S021 is designed for low power consumption and operates with a single supply voltage ranging from +2.7V to +5.25V, making it suitable for a variety of applications requiring efficient and precise analog-to-digital conversion.
