Overview
The MAX11612EUA+ is a low-power, 4-channel, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is packaged in an 8-pin μMAX package and features internal track/hold (T/H), voltage reference, clock, and an I2C-compatible 2-wire serial interface. It operates from a single supply voltage range of 4.5V to 5.5V and is designed for low power consumption, requiring only 670μA at the maximum sampling rate of 94.4ksps. The device also includes an AutoShutdown feature that reduces supply current to less than 1μA at low throughput rates, making it suitable for battery-powered and solar-powered applications.
