General Description
The MAX11205 is an ultra-low-power (< 300FA max active current), high-resolution, serial-output ADC. This device provides the highest resolution per unit power in the industry, and is optimized for applications that require very high dynamic range with low power such as sensors on a 4mA to 20mA industrial control loop. The MAX11205 provides a high-accuracy internal oscillator that requires no external components.
