Overview
The MAX11605EEE+ is a low-power, 8-bit, 12-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is housed in a 16-pin QSOP 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 ranging from 2.7V to 3.6V and consumes only 350µA at the maximum sampling rate of 188ksps. The AutoShutdown feature reduces the supply current to less than 1µA at low throughput rates, making it suitable for battery-powered and solar-powered applications.
