Introduction:

Analog to Digital Converters (ADC) are electronic devices that convert analog signals into digital signals that can be used by computers and other digital systems. One type of ADC is the ADC14155CISQ/NOPB, a high-speed, high-resolution, low-power device that is used in many applications. In this paper, we will discuss the application field and working principle of the ADC14155CISQ/NOPB.

Application Field:

The ADC14155CISQ/NOPB is a single-channel 14-bit conversion precision ADC that is designed for a variety of applications including medical imaging and monitoring, signal processing, data acquisition, and industrial automation. This device is ideal for signal-processing applications that require high-resolution, precise measurement capabilities. It is able to accurately measure the precise voltage levels of sensors, signals, and other equipment.

The ADC14155CISQ/NOPB has a wide range of power requirements that makes it suitable for a variety of applications. This device can be powered from a single 3V to 5.5V power supply, or from a 5V to 12V supply for industrial applications. This makes it well suited for both battery-powered systems and mains-powered systems.

The high-speed, high-resolution features of this device offer significant advantages over other ADC devices. With its fast conversion time of only 1 μs, it enables fast signal processing and analysis in real time. Its high-resolution also allows for precise measurements and better signal-to-noise ratio.

Working Principle:

The ADC14155CISQ/NOPB is a “sample and hold” device, which means that it samples the voltage level of an analog signal and holds the sample until the conversion is complete. The device includes two internal capacitors that charge to the voltage of the analog signal over a known period of time. The voltage to be converted is then kept between the two capacitors until the conversion is complete.

The device measures the voltage of the analog signal by measuring the time it takes for the voltage on the capacitors to equalize. The conversion time is determined by the ratio between the capacitance and the load resistance, as well as the number of bits of resolution needed. Once the conversion is complete, the device applies a “shaping” algorithm to generate the digital output signal.

The ADC14155CISQ/NOPB also features a low-power auto-power down mode that conserves energy when the device is not in use. This feature allows the device to reduce power consumption when it is not actively being used, making it more efficient in battery-powered applications.

Conclusion:

The ADC14155CISQ/NOPB is a high-speed, high-resolution device that is suitable for a wide range of applications. Its low-power, low-voltage requirements make it suitable for battery-powered and mains-powered systems, while its fast conversion time and high-resolution capabilities make it ideal for signal-processing applications that require precise measurements. Its low-power auto-power down mode also makes it more energy efficient.
