Overview
The MAX11101EWC+T is a low-power, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive approximation register (SAR) architecture and includes an input track-and-hold (T/H) circuit. It operates with a single +5V analog supply and has a separate digital supply, allowing direct interfacing with 2.7V to 5.25V digital logic. The MAX11101 is designed for applications requiring high dynamic performance, low power consumption, and compact packaging.
