A data acquisition system is a collective combination of sensors, transducers, and analogue-to-digital converters (ADC), all of which collect, convert, store and send electronic data. ADS8412IPFBRG4, produced by Texas Instruments Incorporated, is one of the ADCs. It is designed for industrial, high accuracy, and high speed data acquisition systems.

The ADS8412IPFBRG4 is a 12-bit, simultaneous sampling ADC that can simultaneously sample and convert up to four channels. It features single-cycle settling and a wide analog input dynamic range of ± 5 V. Additionally, it has an on-chip low-pass, antialiasing filter with 12-dB/octave, 75-kHz 3-pole configuration.

The ADS8412IPFBRG4 provides user-programmable input ranges and gain. The device can sample up to 1 MHz and converts the sampled signals into 12-bit digital codes, making it ideal for high-speed acquisition and control applications. Additionally, it includes two error output pins that indicate the presence of an input overflow (OV) or a code error (CE), and is available in a compact SOIC-14 package.

ADS8412IPFBRG4’s field of application and working principle are discussed in this paper.

Working Principle of ADS8412IPFBRG4

The ADS8412IPFBRG4 is a 12-bit, simultaneous sampling analogue-to-digital converter (ADC) that supports up to four channels. It features single-cycle settling, wide analog input dynamic range of ± 5 V, on-chip low-pass, antialiasing filter with 12-dB/octave, 75-kHz3-pole configuration, as well as an on-chip waveform generator.

When a voltage is applied to the input of the ADC, an analog-to-digital conversion process is triggered and the code converter starts to work. Initially the input voltage is attenuated and then converted into a number sequence which is then sent to the output of the device. The waveform generator allows the user to set up to four different signals that can be written from the waveform memory to the input of the ADC. The waveform generator can also be used to provide different waveforms on the output channels of the ADC.

After the waveform generator is programmed and the waveform is written to the input of the ADC, the codes of that waveform are converted and sent to the output of the ADC. The 12-bit resolution provides the maximum resolution of the input waveform. Additionally, the on-chip low-pass filter with its 12-dB/octave, 75-kHz 3-pole configuration ensures the removal of high frequency components and noise before the signal is applied to the ADC.

The ADS8412IPFBRG4 also includes two error output pins (OV and CE) that indicate the presence of an input overflow or a code error. By using these error output pins, external circuit is easily notified when the ADC is operating in an erroneous condition.

Conclusion

The ADS8412IPFBRG4 from Texas Instruments is an ideal ADC for data acquisition systems. It has a wide range of applications, such as energy monitoring and test and measurement. It features fast settling time, high resolution and low noise, and provides two error output pins for error reporting. The ADS8412IPFBRG4 is an efficient device for high-precision and high-speed data acquisition.
