MAX11046ECB+T

Data Acquisition - Analog to Digital Converters (ADC)

The MAX11046ECB+T is a high-performance, low-power, multi-channel, successive-approximation-register (SAR) analog-to-digital converter (ADC). It can sample up to four separate analog inputs with up to 12 bits of resolution. The differential analog inputs can sample signals up to ±VREF. The ADC can operate in the range of 2.7V to 3.3V with ±VREF ranges from 0V to 1.8V. The MAX11046ECB+T offers low power consumption, making it ideal for battery-powered applications.

Application Field

The MAX11046ECB+T is suitable for a wide range of applications in the consumer, communications, industrial, medical and automotive markets such as digital audio, industrial process control, and motor control. In these applications, it can be used to capture and convert analog signals (such as sound, temperature, pressure, flow, etc.) into digital signals that can be processed and controlled by the application. It can also be used for the acquisition of multiple types of data such as temperature and pressure.

Working Principle

The MAX11046ECB+T uses a successive approximation register (SAR) to convert analog signals into digital values. In this process, the ADC first compares the incoming analog signal to a known reference voltage. Then, it repeatedly adjusts the reference voltage based on each comparison and determines the final digital value by using a SAR algorithm. The analog voltage is sampled at the input of the ADC, converted to digital form and output as a serial bus. The ADC can also be configured to convert the input from a different voltage range.

The MAX11046ECB+T is designed to make the most of the available power, in order to maximize run time for battery-powered applications. It can operate in a low power single-slope conversion mode, where the ADC is powered down after each conversion, or in a burst conversion mode, where the ADC is powered down between conversion blocks to reduce average power consumption. The maximum power consumption in both conversion modes is very low.

Conclusion

The MAX11046ECB+T is an efficient high-performance, low-power multi-channel, SAR ADC. It is ideal for a wide range of applications that require high resolution analog data acquisition, including consumer, communications, industrial, medical and automotive. Additionally, its low power consumption makes it ideal for battery-powered applications.
