Data acquisition generally involves converting analog signals into digital form. Analog to Digital Converters (ADC) are used to effectively achieve this goal, with the ADC1213D080HN/C1,5 being a prominent example. Its application field and working principle will be discussed below.

Application Field

The ADC1213D080HN/C1,5 is generally used in high speed, high reliability, and low noise systems. It is especially well-suited for power supply monitoring and motor control applications due to its advanced sigma-delta modulator and excellent analog performance. Furthermore, having a wide single-supply input voltage range of 2.6 - 11.6 V, it is perfect for applications with limited supply voltage.

Working Principle

ADC1213D080HN/C1,5 is a Sigma-Delta based ADC. Sigma-Delta architecture is a one bit high-resolution architecture that relies on high accuracy and speed of a 24 bits Σ-Δ ADC Modulator coupled with an undersampling scheme. The signal or the noise signal is oversampled in which the noise energy present spread in the signal bandwidth is first reduced by 2-nd order digital filer and then filtered using a digital signal processing filter. Finally, an undersampling scheme is used, where the signal is quantified to the actual resolution. The sampling rate depends on the input signal frequency, characteristics and quality of the digital filters.

The ADC1213D080HN/C1,5 uses a 2.6V-11.6V single supply input and has a wide dynamic range. It employs a differential low noise amplifier, on-chip reference and track/hold, making it suitable for bipolar signal-type applications. The integrated sigma-delta modulator works on a 24 bit sigma-delta architecture, allowing for fast throughput rates of 40 kSPS. Furthermore, the ADC1213D080HN/C1,5 integrates excellent EMI performance, low power consumption and an extended temperature range.

Conclusion

The ADC1213D080HN/C1,5 fulfills a variety of application needs, including low noise single supply, fast sampling rate (40 kSPS), and EMI performance. Its sigma-delta architecture provides high resolution and accuracy, which is necessary for power supply monitoring and motor control applications. Furthermore, its single supply input can handle a wide range of voltages, making the ADC1213D080HN/C1,5 a great fit for many applications with limited voltage supply.
