Analog to Digital Converters (ADCs) are digital devices that convert analog signals into digital information. The most common type of ADC is the Pulse-Code Modulation (PCM) system, which uses ADC converters to convert analog signals into digital signals. The PCM technique was developed in the 1950s to allow telephone signals to be digitized and transmitted. In the realm of data acquisition, the application of an ADC is comparatively straightforward. By capturing instantaneous analog readings, an ADC can provide digitized representations of a single physical variable.

One example of this is the application of an ADC in the form of the AMC1203PSA, a 12-bit, low power analogue-to-digital converter. The device is designed for use in medical instrumentation, energy management, and factory automation systems, among other fields. It offers a resolution of up to 0.87mV and a high-speed update rate of up to 2.4Msps (8-bit resolution), with a user-defined gain setting.

The AMC1203PSA utilizes a combination of analog and digital circuits to sample, convert, and output the analog signals that are inputted into it. It has an onboard channel converter which shifts the input signals to within a specified range, allowing for increased resolution. The device then converts the analog signals into a digital format through an external analog to digital converter. This digital data is then sent to the memory where it is stored until it is needed.

Once stored in the memory, the data can then be fed into the digital signal processor. The digital signal processor has the capability to turn the data into power levels, or to other values that can be interpreted by the user. This conversion process is controlled by a clock which is triggered when the input signal changes value. At this point, the ADC is able to measure and record the change in voltage accurately.

AMC1203PSA is capable of conversion speeds up to 2.4Msps, making it suitable for use in high-speed applications. Additionally, it features internal auto-range to ensure the highest available resolution, adjustable input range and gain settings, and a very low power consumption of 1.1mA at 2.4Msps. It also has an on-chip precision reference, allowing for an extremely accurate conversion rate.

The application of the AMC1203PSA is ideal for any number of data acquisition applications. With its low power consumption, fast data conversion rate, and high-resolution capability, the device is suitable for a wide range of uses. This makes it an ideal choice for medical instrumentation, energy management, factory automation, and other similar fields.
