Overview
The MAX1162CCUB, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 16-bit analog-to-digital converter (ADC) designed for high-performance and low-power applications. This ADC features a successive-approximation 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 device is ideal for battery-powered and data-acquisition applications, as well as other circuits with demanding power consumption and space requirements.
