Maxim Integrated MAX11200 24-Bit
Ultra-Low-Power ADCs

Maxim Integrated's MAX11200 24-bit ultra-low-power (<300 µA active current) serial output analog-to-digital converters (ADCs) with GPIO provide the highest resolution per unit power in the industry. These Maxim Integrated data converters 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 ADCs to be used with high-impedance sources without compromising available dynamic range or linearity. MAX11200 ADCs 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 include four GPIOs that can be used for external mux control.
