Overview
The MAX1165AEUI+T is a low-power, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1165/MAX1166 family, known for their high-performance and low power consumption, making them ideal for battery-powered and space-constrained applications.
The MAX1165AEUI+T features a successive-approximation (SAR) conversion technique with an inherent track-and-hold (T/H) stage, providing accurate and high-speed conversions. It operates from a single +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply, and it includes an internal 4.096V reference or the option to use an external reference.
