Introduction to MAX199BCWI+T Application Field and Working Principle

The MAX199BCWI+T (Low-Power, Self-Calibrating, Low-Noise, 18-Bit SAR ADCs with Built-In Temperature Sensor) is a single-channel 18-bit successive-approximationregister analog-to-digital converter (SAR ADC) with a built-in temperature sensor and high-reliability calibration system. This product combines the features of high-speed sample rate down to 5µs, low-noise 18-bit conversion, and a wide-input voltage range from 0 V to 3.7V.

The MAX199BCWI+T is typically used in a wide range of applications in data acquisition, positioning, medical, and industrial process control systems. It is designed for a variety of applications including but not limited to audio and video processing, radar, remote sensing , and scientific equipment that depend on the accuracy of the data conversion and temperature sensing.

Working Principle:

The MAX199BCWI+T ADC operates by sampling an input voltage and comparing it to an internal reference voltage, which is generated from an on-chip bandgap reference and boosted internally. The output of the ADC is proportional to the input voltage applied. As the reference voltage is increased in successive steps and compared to the input voltage, the ADC is able to determine the exact analog value and encode it as a binary number. In addition, the ADC is configured with a built-in temperature sensor and integrated to an internal calibration system. The output temperature data is converted to an equivalent voltage and can be monitored in real time.

The MAX199BCWI+T provides high resolution and fast start-up time, allowing more accurate monitoring of ever-changing temperatures. The ADC also offers low output noise, wide voltage range and excellent common-mode rejection ratio (CMRR). It also has an integrated temperature sensor with a wide dynamic temperature range that makes it suitable for a variety of temperaturesensitive applications.
