MAX11210:24-Bit, Single-Channel, Ultra-Low Power, Delta-Sigma ADCs with GPIO

24-Bit ADC Offers Industry-Leading, Noise-Free Resolution Per Unit Power

The MAX11200/MAX11210 are ultra-low-power (< 300µA active current), high-resolution, serial output ADCs. These devices provide the highest resolution per unit power in the industry, and are optimized for applications that require very high dynamic range with low power, such as sensors on a 4mA to 20mA industrial control loop. Optional input buffers provide isolation of the signal inputs from the switched capacitor sampling network allowing these converters to be used with high-impedance sources without compromising available dynamic range or linearity. The devices 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 100dB rejection of 50Hz or 60Hz line noise. The devices are configurable using the SPI interface and are available in a 16-pin QSOP package.
