MAXIM MAX11212AEUB+

The MAX11212 is an ultra-low power (< 300μA 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 MAX11212 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 MAX11212 provides a simple 2-wire serial interface in the space-saving, 10-pin μMAX package. The MAX11212 operates over the -40°C to +85°C temperature range.
