MAX11201 Datasheet | Maxim Integrated

Description The MAX11201 is an ultra-low-power (< 320FA 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 4m A to 20m A industrial control loop. The MAX11201 provides a high-accuracy internal oscillator that requires no external ponents. When used with the specified data rates, the internal digital filter provides more than 100d B rejection of 50Hz or 60Hz line noise. The MAX11201 provides a simple 2-wire serial interface in the space-saving, 10-pin FMAXM package. The MAX11201 operates over the -40NC to +85NC temperature range.
