Analog Devices / Maxim Integrated MAX11202 & MAX11212 Serial Output ADCs

Analog Devices MAX11202 and MAX11212 Serial Output ADCs feature high resolution per unit power. This ultra-low-power (<300µA max active current), high-resolution, serial output ADC is optimized for applications that require high dynamic range with low power such as sensors on a 4mA to 20mA industrial control loop. The MAX11202 and MAX11212 provide 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 ADI MAX11202 and MAX11212 Serial Output ADCs provide a simple 2-wire serial interface in the space-saving, 10-pin µMAX package and operate over the -40°C to +85°C temperature range.
