MAX11201AEUB+

The MAX11201AEUB+ is a 24bit, single channel, ultra low power, delta-sigma analogue to digital converter (ADC) with buffer in 10 pin µMAX package. This high resolution, serial output ADC operates from 2.7V to 3.6V analogue and 1.7V to 3.6V digital supply range. It provides highest resolution per unit power in industry and it is optimized for applications that require very high dynamic range with low power such as sensors on 4mA to 20mA industrial control loop. This MAX11201 provides high accuracy internal oscillator that requires no external components. When used with the specified data rates, the internal digital filter provides more than 100dB rejection of 50Hz or 60Hz line noise. The device is used in sensor measurement (temperature and pressure), portable instrumentation, weigh scales and battery applications.
