Working Principle

The AD9628BCPZRL7-125 is an analog-to-digital converter (ADC) which converts an analog input signal into a digital output signal. The device works by first passing the analog input signal through an appropriate amplifier. The amplifier amplifies the input signal and provides the necessary level of gain before converting the signal into a digital representation. The amplified analog data is then sampled at a predetermined rate and converted into binary numbers.

The output data is then further processed by the device’s digital signal processing (DSP) block. This includes performing gain, filtering, and other signal conditioning functions. The data is then formatted according to the user’s specified data output format and sent to the output pins of the device.

Application Fields

The AD9628BCPZRL7-125 is well-suited for a variety of data acquisition and signal processing applications, including medical imaging, industrial control, instrumentation and test, automotive, and defense and aerospace. This device is ideal for applications that require high resolution and fast throughput, such as ultrasound imaging, digital video, 3D mapping, and object recognition.
