MAX11203EEE+ (MAXIM INTEGRATED PRODUCTS)

The MAX11203EEE+ is a 16bit, single channel, ultra low power, delta sigma ADC with programmable gain and GPIO in 16 pin QSOP package. It is an ultra low power (< 300µA 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. Optional input buffers provide isolation of the signal inputs from the switched capacitor sampling network allowing this converter to be used with high-impedance sources without compromising available dynamic range or linearity. The device 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 100dB rejection of 50Hz or 60Hz line noise. The device is configurable using the SPI interface.
