Maxim Integrated MAX11208AEUB

Description
The MAX11208 is an ultra-low-power, high-resolution, serial-output ADC. It 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 MAX11208 provides a high-accuracy internal oscillator that requires no external components. When used with the specified data rates, the internal digital filter provides more than 80dB rejection of 50Hz or 60Hz line noise. The MAX11208 provides a simple 2-wire serial interface in the space-saving, 10-pin μMAX® package. The MAX11208 operates over the -40°C to 85°C temperature range.
