Overview
The MAX1037LEKA+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 family and is designed for high-performance and low-power applications. It features internal track/hold (T/H), voltage reference, clock, and an I²C-compatible 2-wire serial interface. The MAX1037LEKA+T operates from a single supply voltage ranging from 2.7V to 3.6V and consumes only 350µA at the maximum sampling rate of 188ksps. The device includes Auto-Shutdown™, which powers down the ADC between conversions, reducing the supply current to less than 1µA at low throughput rates.
