Overview
The MAX1162CEUB+T is a low-power, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive-approximation register (SAR) architecture and is designed for high-performance, low-power applications. The MAX1162 operates with a single +5V analog supply and a separate digital supply, allowing direct interfacing with +2.7V to +5.25V digital logic. It is particularly suited for battery-powered and data-acquisition applications due to its excellent dynamic performance, low power consumption, and small package size.
