Overview
The MAX1062BEUB+T is a 14-bit, low-power analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC features a successive approximation register (SAR) architecture and is designed for high-speed and low-power applications. 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 device is particularly suited for battery-powered and data-acquisition applications due to its excellent dynamic performance, low power consumption, and small package size (10-pin µMAX®).
