Overview
The MAX117EAI+T is a microprocessor-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX117 series, which includes 8-channel ADCs designed for low-power and high-speed applications. The MAX117EAI+T operates from a single +3V supply and utilizes a half-flash technique to achieve a conversion time of 1.8µs, resulting in a sampling speed of 400ksps. It features a power-down mode that reduces current consumption to 1µA, making it suitable for battery-powered systems and other low-power applications.
