MAX11206EEE+

The MAX11206EEE+ is a 20bit, single channel, ultra low power, delta sigma ADC with programmable gain and GPIO in 16 pin QSOP package. This device provides highest resolution per unit power in industry and optimized for applications that require very high dynamic range with low power, such as sensors on a 4mA to 20mA industrial control loop. The device provides a high-accuracy internal oscillator that requires no external components. When used with the specified data rates, internal digital filter provides more than 100dB rejection of 50Hz or 60Hz line noise. The device is configurable using SPI interface and includes four GPIOs that can be used for external mux control. The ADC includes digital programmable gain of 1 to 128. It is used in sensor measurement (temperature and pressure) and weigh scales.
