Overview
The MAX1292ACEG is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1290/MAX1292 series, known for its low power consumption, high-speed operation, and versatile interface options. The MAX1292 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. It is particularly suited for applications requiring high dynamic performance, low power consumption, and compact packaging.
