Product Details
The MAX11201 is an ultra-low-power (< 320µA 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 MAX11201 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 100dB rejection of 50Hz or 60Hz line noise. The MAX11201 provides a simple 2-wire serial interface in the space-saving, 10-pin µMAX® package.
The MAX11201 operates over the -40°C to +85°C temperature range.
