MAX11203EEE+ Description

The MAX11203EEE+ is an ultra-low-power (< 300µA active current), high-resolution, serial-output ADCs. The device provides the highest resolution per unit of power in the industry. It is optimized for applications that require a 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.
