Data Acquisition is a process of gathering data from either physical or virtual sources and obtaining meaningful information from the data. The field of Data Acquisition has developed rapidly in the past few decades and has become a crucial part of many industries. This article will focus on the application field and working principle of AMC 1204DWR, a specialized Data Acquisition device.

The AMC 1204DWR is a high-speed, 16-bit analog-to-digital converter (ADC) and digital-to-analog converter (DAC) that is well-suited for professional applications involving high-precision measurements. Designers of measurement systems, including sonic range imaging and infrared, commonly use the device. It also finds application in laboratory and field measurement of electrical and environmental parameters.

The 1204DWR incorporates a 16-bit successive-approximation register (SAR) ADC and a 16-bit DAC. It is programmed using a Serial Data Interface (SDI) connection, with commands sent as ASCII-formatted frames. On the input side, the ADC accepts signals from 0 to 3.3V. It provides resolutions ranging from 12 bits at 30ksps to 14 bits at 15ksps. It achieves an accuracy of 0.0005%. On the output side, the DAC has 45dB of dynamic range, a programmable-gain amplifier, and a reference voltage to sum external signals before feeding them to the output. It also has a mode to adjust the waveform in the middle of a measurement, allowing for fine control over the waveform.

The 1204DWR can be set up using a software configuration tool. This is a graphical application that allows the user to select the parameters they want: sampling rate, resolution, gain, input voltage range, etc. Once programmed, the device is ready to measure and record real-world signals in the desired environment: outdoors, on a moving platform, at high temperatures, etc. Its compact form factor makes it suitable for applications with less space, such as automotive, aerospace, and medical electronics.

The 1204DWR is equipped with embedded features and sophisticated algorithms to reduce noise and improve accuracy. The input signal is low-pass filtered to avoid aliasing and reduce noise. The ADC has also built-in oversampling and decimation to further reduce noise. Finally, the ADC incorporates a patented design, enhancing linearity and reducing errors.

In summary, the AMC 1204DWR is a specialized Data Acquisition device designed for high-precision measurements. It delivers 16-bit resolution and accuracy with an embedded set of features to reduce noise and improve linearity. The device is suitable for a wide range of applications from laboratory measurements to measurements taken on the move, in extreme temperatures or in limited spaces. Overall, the 1204DWR is an ideal solution for applications that require high accuracy and repeatability.
