PCM1720E Application Field and Working Principle

The PCM1720E is a special purpose analog-to-digital converter (ADC) from Texas Instruments. It is a feature-rich, low-power ADC that is well-suited for data acquisition applications in extreme temperature environments. This makes it a popular choice for applications that require precision conversion in harsh environments.

The PCM1720E has a 16-bit resolution, a sample rate of up to 105 kHz, and a temperature range of -45°C to +125°C. It has an on-chip low-noise amplifier, an on-board reference voltage supply, a temperature compensated oscillator, and an analog multiplexer. The PCM1720E includes an integrated phase-locked loop (PLL) which guarantees excellent phase linearity and ensures that all components of its signal remain in phase. This feature helps improve the accuracy of the measured results.

Application Fields

The PCM1720E is a great choice for applications in which precision and accuracy are top priorities. It has been used in various industrial applications such as signal filtering in industrial processes, weather forecasting, smart home appliances, and automotive signal generation. The device can also be used in data acquisition systems for medical imaging and other professional audio applications.

Working Principle

The PCM1720E works by converting an analog input signal into a digital representation. The ADC starts by using the on-chip amplifier to boost the incoming voltage. The amplified voltage is then sent to the digital multiplexer which selects the desired input voltage. Finally, the selected input voltage is sent to the low-noise analog-to-digital converter which samples the signal and converts it into a digital representation.

The PCM1720E also uses its on-board temperature-controlling mechanism to ensure that the analog-to-digital conversion is done with consistent accuracy across all measured temperatures. This is done by controlling the power supply of the device’s analog circuit and matching it to the reference voltage generated by the on-board reference supply. The temperature-controlled analog circuit helps reduce any changes in the measured result due to temperature variations.

Conclusion

The PCM1720E is a feature-rich, low-power ADC that is well-suited for data acquisition applications in extreme temperature environments. It has a 16-bit resolution and a sample rate of up to 105 kHz. The device also includes integrated features such as a low-noise amplifier, an on-board reference voltage supply, a temperature compensated oscillator, and an analog multiplexer. Additionally, the device’s on-board temperature-controlling mechanism helps ensure consistent accuracy across all measured temperatures. The PCM1720E is a great choice for precision, accuracy-focused applications, including signal filtering in industrial processes, weather forecasting, smart home appliances, automotive signal generation, and medical imaging.
