General Description
The MAX11203/MAX11213 are ultra-low-power (< 300µA active current), high-resolution, serial-output ADCs. These devices provide the highest resolution per unit power in the industry, and are optimized for applications that require very high dynamic range with low power, such as sensors on a 4mA to 20mA industrial control loop.
