Overview
The MAX1162ACUB+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 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 and data-acquisition applications due to its excellent dynamic performance, low power consumption, and compact package size.
