Analog to Digital Converters (ADC) are essential components of modern electronics from consumer systems to industrial automation and process control, allowing accurate conversion of analog signals into digital counterparts that can be used, recorded and transmitted. In this article we will look at the AD7490BRU-REEL and the application field and working principle it provides.

The AD7490BRU-REEL is a low power, multi-channel analog to digital converter (ADC) with integrated Digital-to-analog Converter (DAC). This ADC provides a wide bandwidth and is optimized for signals that require fast conversion with low power consumption. The AD7490BRU-REEL provides 8- and 10-bit resolutions and can sample up to 100kHz. It has a low voltage range of 2.7V to 4.1V, making it suitable for low power and cost sensitive applications.

The AD7490BRU-REEL is suitable for a range of applications, including process control, industrial automation, medical and consumer applications. The ADC is used in medical monitoring and measurement applications, including patient monitoring, vital sign monitoring and medical imaging systems. In industrial automation, the ADC can be used for process control, controlling motors and valves, as well as for monitoring environmental conditions. In consumer applications, the ADC can be used for digital music systems, audio-video applications, gaming and home security.

The working principle of the AD7490BRU-REEL is the same as many other ADC’s. The ADC converts the analog signal it is fed into its digital equivalent, breaking it down into a series of discrete values, representing each voltage level. The ADC uses an internal reference voltage (VREF) to determine the full-scale range of the analog signal. The ADC then divides up its input range into a series of ‘steps’ which it can use as codes to represent each voltage level. The ADC then measures the voltage at its input and assignes a code to the voltage level.

In addition to providing its ADC functionality, the AD7490BRU-REEL also provides integrated digital-to-analog conversion. This allows the ADC to be used for digital/analog signal conversion. The DAC is based on a 12-bit delta-sigma architecture, providing higher resolution than most Delta-Sigma DACs. It is capable of converting its output signal at up to 24kHz and has a latency of 0.75µs.

The AD7490BRU-REEL provides an accurate and efficient solution for analog to digital signal conversion. Its low voltage requirement and integrated DAC make it suitable for a range of applications including medical, industrial automation, process control and consumer applications. Its fast conversion rate, low power consumption and wide bandwidth make it suitable for a range of applications requiring accurate signal conversion.
