Overview
The MAX1039AEEE+T is a low-power, 8-bit, multichannel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1036–MAX1039 series, which features internal track/hold (T/H), voltage reference, clock, and an I²C-compatible 2-wire serial interface. The MAX1039AEEE+T is specifically designed with twelve analog input channels, making it suitable for a variety of applications requiring multiple input channels.
The device operates from a single supply voltage ranging from 2.7V to 3.6V and consumes only 350µA at the maximum sampling rate of 188ksps. It also features AutoShutdown™, which powers down the device between conversions, reducing the supply current to less than 1µA at low throughput rates. This makes it highly efficient for battery-powered and low-power applications.
