1 / 14 page 18-Bit, Single-Channel, Ultra-Low Power, Delta- Sigma ADC with 2-Wire Serial Interface MAX11212 19-5247; Rev 0; 4/10 Ordering Information Selector Guide General Description The MAX11212 is an ultra-low power (< 300FA 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 MAX11212 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. The MAX11212 provides a simple 2-wire serial interface in the space-saving, 10-pin FMAXM pack- age. The MAX11212 operates over the -40NC to +85NC temperature range.
