Overview
The MAX11600EKA+T is a low-power, 8-bit, multi-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX11600–MAX11605 series, which features internal track/hold (T/H), voltage reference, clock, and an I2C-compatible 2-wire serial interface. It operates from a single supply voltage ranging from 2.7V to 3.6V or 4.5V to 5.5V, making it versatile for various applications. The MAX11600EKA+T is designed for high efficiency, consuming only 350µA at the maximum sampling rate of 188ksps and reducing supply current to less than 1µA during low throughput rates due to its Auto-Shutdown™ feature.
