Overview
The MAX1156BEUP+T is a 14-bit, low-power, successive-approximation analog-to-digital converter (ADC) produced by Maxim Integrated, now part of Analog Devices Inc. This device is designed for high-performance, battery-powered data-acquisition applications. It features a byte-wide parallel interface, automatic power-down, and a factory-trimmed internal clock. The MAX1156BEUP+T 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.
