ADS1672IPAG Application Field

ADS1672IPAG is widely used in point-of-load (PoL) regulation, power management, high-speed data acquisition, and similar applications. In these applications, the device is relied on to provide high resolution and precision data conversion.As mentioned, the device is built with an integrated multi-channel converter, which can accommodate two differential or four single-ended analog input channels. This makes it an ideal choice for applications that require multiple measurements.The adjustable output scaling allows the results to be adjusted to the most accurate value and make them easier to use with other components.

ADS1672IPAG Working Principle

The ADS1672IPAG works on the principle of analog-to-digital conversion. In this process, the analog signal is first converted into a digital data, which can then be used for further processing and analysis.The device is built with a two-channel, 12-bit analog-to-digital converter (ADC). The two channels can support both differential and single-ended inputs, allowing for high-resolution data acquisition.The output of the ADC is fed to a sample-and-hold circuit which stores the sample data. A fractal filter is then used to reduce noise from the sampled data.The data is then fed to a digital-to-analog converter (DAC) where it is converted into a digitally-controlled voltage that is then sent to the output stage.

The output stage utilizes a programmable gain amplifier (PGA) to adjust the gain of the output signal. The adjustable output scaling allows the user to adjust the output scaling to the most accurate value, making it easier to use with other components.The output of the PGA is sent to a low pass filter (LPF) which removes any residual noise from the signal.The filtered signal is then sent to the output. Furthermore, the ADC can be used as an integrate-and-forget circuit to reduce power consumption during standby.

Conclusion

ADS1672IPAG is a fully-integrated, low-power, two-channel 12-bit analog-to-digital converter.It offers a wide range of features which make it suitable for a variety of applications, such as point-of-load regulation, power management, high-speed data acquisition, and similar applications where a high resolution is necessary. Additionally, the device’s adjustable output scaling and low power standby mode add to its versatility.The device works on the principle of analog-to-digital conversion which is used to convert analog signals into digital data.Finally, it relies on a sample-and-hold circuit, a fractal filter and a programmable gain amplifier to adjust the gain of the output signal.
