Overview
The MAX11101 is a low-power, 14-bit analog-to-digital converter (ADC) produced by Maxim Integrated, now part of Analog Devices Inc. This ADC features a successive approximation architecture and is designed for applications requiring high resolution, low power consumption, and compact packaging. The MAX11101 operates with a single +5V analog supply and has a separate digital supply, allowing it to interface directly with digital logic ranging from 2.7V to 5.25V. It is particularly suited for battery-powered devices, data-acquisition systems, and other applications where power efficiency and space are critical.
