The MAX11208AEUB+ is a 20bit, single channel, ultra low power, delta-sigma ADC with 2-wire serial interface in 10 pin μMAX package. 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 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. Typical applications include sensor measurement (temperature and pressure), portable instrumentation, battery applications and weigh scales.
