Overview
The MAX11200EEE+ is an ultra-low-power, high-resolution, single-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. These devices are optimized for applications requiring very high dynamic range with low power consumption, making them ideal for use in sensors on industrial control loops, such as 4mA to 20mA loops.
The MAX11200EEE+ offers the highest resolution per unit power in the industry, featuring a 24-bit delta-sigma ADC architecture. The device includes optional input buffers that isolate the signal inputs from the switched capacitor sampling network, allowing it to be used with high-impedance sources without compromising dynamic range or linearity.
