Overview
The MAX1264AEEG+ is a low-power, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive-approximation ADC architecture and is designed for high-performance and low-power applications. It operates with a single +5V analog supply and includes a VLOGIC pin that allows it to interface directly with a +2.7V to +5.5V digital supply. The MAX1264AEEG+ is particularly suited for battery-powered and data-acquisition systems due to its excellent dynamic performance, low power consumption, and compact package size.
