Overview
The MAX1264AEEG+T is a low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1262/MAX1264 family, known for its high performance, low power consumption, and versatility. The MAX1264 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 ideal for battery-powered and data-acquisition applications, as well as other circuits with demanding power consumption and space requirements.
