Data Acquisition - Analog to Digital Converters (ADC)

Analog-to-Digital Converters (ADCs) are essential components in a wide range of data acquisition and embedded system application designs. They offer the ability to read in analog signal levels, and measure them with high accuracy and speed in digital environments. The AD7893ANZ-10 application field is an example of an analog-to-digital converter and this article will explore its working principle and application field.Analog-to-digital converters (ADCs) are used for converting analog signals into digital signals for more precise, faster, and less complex signal processing with digital circuits, such as microcontrollers and digital signal processors (DSPs). An ADC reads the analog signal, which is a time- and voltage- varying continuous wave, and produces a discrete quantity of signals that are analogous to the original waveform.The AD7893ANZ-10 is an integrated high-speed resolution, 10-bit analog-to-digital converter that can convert analog voltages into 10-bit binary values with accuracy and speed. This ADC is ideal for applications that need low power consumption and reliable analog-to-digital conversion, including battery powered portable data acquisition devices, medical systems, audio, and instrumentation systems. The AD7893ANZ-10 operates on a 4.0V to 5.5V single supply and can convert analog input signals of 0V to 2.5V. It has a high-speed conversion rate of 15MSPS and is capable of sampling input voltages up to 80ns. The converter has a low differential nonlinearity (DNL) and no missing codes, which allows it to accurately measure small voltage changes. Its low power operation of 1.3mW and small size makes it ideal for high-density portable systems.The main features of the AD7893ANZ-10 include low power consumption and low supply voltage. It has an on-chip voltage reference and clock oscillator, which provide for an easy-to-use, low part count solution for converting analog signals to digital. The AD7893ANZ-10 also features a flexible input range, letting the user select from four input ranges. The AD7893ANZ-10 uses a Successive Approximation (SAR) architecture to convert the analog input to digital output. The SAR works by comparing a voltage reference to the input voltage, and then successively approximating the voltage until it matches the reference voltage. The SAR outputs the digital code corresponding to the approximated voltage. The higher the resolution, the more accurate the conversion is, and the higher the speed of ADC will be. The AD7893ANZ-10 is ideal for analog-to-digital conversion applications because of its low power operation, wide range of input voltage, fast conversion speed and low differential non-linearity. Its features make it well suited for battery powered systems, such as portable data acquisition, medical, audio and automotive systems, where size and accuracy are key considerations. It is also suitable for applications requiring cost effectiveness, such as instrumentation systems, motor control systems and consumer products.In summary, the AD7893ANZ-10 is an integrated analog-to-digital converter that can convert analog voltages into 10-bit binary representation with accuracy and speed. It is designed for low power applications requiring fast conversion and a small footprint. The on-chip voltage reference and clock oscillator provide a low part count solution making it ideal for applications in instrumentation, portable data acquisition, automotive, medical, audio and consumer products. Its features, such as its input range, conversion speed and low differential non-linearity make it an excellent choice for any application requiring analog-to-digital conversion.
