Overview
The MAX1168BEEG+T, produced by Analog Devices Inc./Maxim Integrated, is a low-power, multichannel, 16-bit analog-to-digital converter (ADC). This device features a successive-approximation ADC architecture and is designed for applications requiring high precision and low power consumption. The MAX1168 operates with a single +5V analog supply and has a separate digital supply, allowing direct interfacing with +2.7V to +5.5V digital logic. It includes an integrated +4.096V reference, a reference buffer, an internal oscillator, and automatic power-down capabilities. The device is particularly suited for control and data-acquisition operations due to its excellent dynamic performance and low power consumption.
