Overview
The MAX1292BEEG+ is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1290/MAX1292 family, known for its low power consumption, high dynamic performance, and ease of use. It operates with a single +5V analog supply and features a VLOGIC pin that allows it to interface directly with a +2.7V to +5.5V digital supply. The MAX1292BEEG+ is ideal for applications requiring high precision and low power, such as battery-powered devices, data-acquisition systems, and industrial control systems.
