Data Acquisition is an increasingly critical aspect of how information systems are being designed and implemented, particularly in the life sciences and certain special purpose applications. In an effort to improve accuracy and precision, the data acquisition system and engineering have been exploring new ways to measure, store and process such information. The PCM4202DB is an application field and working principle-specific device that employs direct sampling technology, allowing designers to increase the speed, accuracy and resolution of their systems. This article will explore the application fields and working principles of the PCM4202DB.

What Is the PCM4202DB?

The PCM4202DB is a high-precision, direct-sampling analog-to-digital converter (ADC). It is used for applications where the resolution and accuracy of the conversion process is essential. The device is capable of sampling inputs up to 24-bits of resolution. This resolution is provided through various sampling rates, ranging from 2Mbps to 200Msps. The device also features a total harmonic distortion (THD) of less than -60 dB and a signal/noise (S/N) ratio of 80 dB or higher.

Additionally, the PCM4202DB is especially effective at processing the wide range of data speeds, voltage levels and types of input signals necessary to service today’s rapidly expanding range of applications. Its wide bandwidth, capability to work with a wide range of input signals and support for multiple-bit resolutions makes it ideal for a variety of applications in the life sciences, metrology, automotive, navigation and other specialized engineering areas.

Application Fields and Working Principles

The PCM4202DB is used for a variety of application fields, including life sciences, metrology, automotive, industrial automation, navigation, and other specialized engineering areas. Its direct sampling capabilities make it highly effective in processing a variety of input signals with high speed, accuracy, and precision. Because of this, it is commonly used in:

• Designing high-precision continuous-wave Doppler systems for medical applications.
• Developing high-precision automotive ADAS (Advanced Driver Assistance Systems).
• Data acquisition and control systems used in industrial automation and process control.
• High-precision sampling of signals in medical and research laboratories.
• Processing of signal inputs for navigation systems in autonomous vehicles.

The PCM4202DB is a two-stage analog-to-digital converter. The first stage is a charge-to-voltage conversion stage, utilizing a capacitor array and analog-to-digital conversion (ADC) clocking. This stage is used to take a charge rate- or voltage-based input signal and convert it into a voltage-based output. This is followed by a second stage, referred to as the recursive averaging stage, which allows the device to accurately sample and average an input signal over time. This is followed by a final output stage, in which the sample value is then quantized with a digital-to-analog converter (DAC).

The PCM4202DB is also designed with a wide-range of error correcting tools, such as offset and gain drift, reset of front and back ends, and low-level sampling, ensuring high precisions and accuracy. Additionally, the device is designed to minimize distortion and noise pick up, and provides the user with a high level of flexibility when it comes to choosing the specific frequency, resolution and accuracy of the samples.

Benefits of PCM4202DB

The PCM4202DB offers a number of benefits for designers, including high resolution and accuracy, as well as wide sampling frequencies for a variety of applications. Other benefits include:

• Low power consumption makes the device ideal for battery-driven applications.
• A high degree of flexibility for user input.
• High-precision clock sources for reliable operation.
• High-reliability in operation and accuracy of results.
• Robust design and built-in protection against noise and interference.
• Compact form factor makes it ideal for many space-restricted applications.

The PCM4202DB allows designers to leverage its innovative direct sampling technology to build data acquisition systems that are faster, more accurate, more reliable and higher performance than ever before. It is a robust, reliable and effective ADC device, used in a variety of applications.
