Overview
The MAX1177CCUP+T, produced by Analog Devices Inc./Maxim Integrated, is a 16-bit, low-power, successive-approximation analog-to-digital converter (ADC). This device is designed for high-performance, battery-powered data-acquisition applications. It features automatic power-down, a factory-trimmed internal clock, and a byte-wide parallel interface. The MAX1177 operates from a single +4.75V to +5.25V analog supply and has a separate digital supply input for direct interface with +2.7V to +5.25V digital logic. The device accepts an analog input voltage range from 0 to +10V, making it suitable for various industrial, instrumentation, and medical applications.
