Overview
The MAX1162AEUB+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 ADC architecture, automatic power-down, and a fast 1.1µs wakeup time. 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 MAX1162 is designed for applications requiring high dynamic performance, low power consumption, and compact packaging, making it ideal for battery-powered and data-acquisition systems.
