The PS9551AL4-AX is an high-precision analog-to-digital signal conversion (ADC) chip and is versatile in its application to a wide variety of signal measurement and signal processing applications. It is the ideal choice for industrial sensors and signal conditioning systems, such as automotive applications, medical imaging, and aerospace and defense industry applications.

The PS9551AL4-AX is a low-noise, low-jitter, high-precision A/D converter, designed to convert analog inputs into digital outputs. It utilizes a 14-bit ADC which can provide up to 16384 different digital codes (14-bits x 2^14=16384). It is capable of both simultaneous sampling and serial data acquisition of up to 16384 data points per channel per sample period.

The main application field for the PS9551AL4-AX is signal acquisition and signal conditioning. Other applications include data logging, test and measurement, motion sensing, industrial control, and video and imaging.

The working principle of the PS9551AL4-AX is quite simple. It converts analog signals into digital signals through the process of sampling and quantizing. The chip takes in the analog signal at a sample rate of up to 16384 times per second and then quantizes it into a digital signal with a resolution of up to 14 bits.

The chip utilizes a switching capacitor filter chain, which consists of a chain of switchable high pass stages. This filter chain samples the incoming signal, removes any noise present in the analog signal and gives an output through an array of digital-to-analog converters (DACs). Finally, the signal is then digitized by a 14-bit ADC, which is capable of producing up to 16384 different digital codes.

The PS9551AL4-AX is a highly versatile and reliable A/D converter, and is preferred in many industrial and commercial applications, including automotive, medical imaging, and aerospace, for its high precision and accuracy in signal processing.
