Overview
The MAX1036LEKA, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 8-bit, multichannel analog-to-digital converter (ADC). 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 MAX1036LEKA specifically has four analog input channels and operates from a single supply voltage ranging from 2.7V to 3.6V or 4.5V to 5.5V, depending on the model variant. It is designed for high efficiency, consuming only 350µA at the maximum sampling rate of 188ksps and reducing to less than 1µA in auto-shutdown mode at low throughput rates.
