Analog-to-digital converters (ADCs) have been in the market for a while and can be used to convert an analog signal to a digital output. These converters are helpful in digital applications, where analog input can be converted to digital signals for processing and further analysis. The AD7853LBRZ-REEL is one such ADC which offers a wide range of applications and features. This article will go into detail about the different application fields and the working principle behind the AD7853LBRZ-REEL ADC.

Applications of the AD7853LBRZ-REEL

The AD7853LBRZ-REEL ADC can be used for a variety of applications, from medical and automotive to telecommunication, broadcasting and industrial control. The analog input can be used in the medical field for sensors like blood pressure and ECG, automotive applications for fuel level, engine control, and anti-lock brakes, telecommunication for signal line control and modems, broadcasting for signal metrics, and in industrial control for measuring temperature or flow.The AD7853LBRZ-REEL is also suitable for applications that require AC signal measurements. It has been designed to detect and digitize signals over a wide frequency range, making it useful for measurement and digital processing of dynamic signals. The ADC also has a built-in excitation stage that can provide a dynamic signal range which allows more precise signal measurements. The AD7853LBRZ-REEL also has low power consumption, making it suitable for battery-operated systems.

Working Principle

The dual-channel, 8-bit AD7853LBRZ-REEL ADC has an input range of +2.4V to VDD (5V). It converts an analog input signal into a digital data stream of 8 bits each, outputting the data on its symmetric TTL/CMOS compatible output pins. The ADC utilizes successive approximation techniques to convert the analog input signal into its digital equivalent. The successive approximation technique is a method in which the ADC starts by comparing the analog input with a predetermined reference voltage, and then gradually reduces the reference voltage until it matches the analog input voltage. This process is repeated multiple times until the correct digital output is achieved.Other features of the AD7853LBRZ-REEL include the zero-drift auto-zeroing function, programmable gain amplifier, and an extremely low EMI emission. The auto-zeroing function helps to eliminate DC errors that can arise from offset errors, gain error, and asymmetrical currents in the input signal source. The programmable gain amplifier, on the other hand, allows the user to program a specific gain prior to the analog-to-digital conversion. This helps to reduce the amount of noise present in the digital output. Furthermore, the low EMI emission feature helps to suppress EMI noise emitted from the converter, which can cause interference with other electronic components in the system.

Conclusion

The AD7853LBRZ-REEL is a dual-channel, 8-bit ADC that is suitable for a variety of applications. With its wide input range, low power consumption, built-in excitation stage and auto-zeroing function, it is ideal for accurately converting analog signals into digital data. The low EMI emission feature makes it suitable for a system with multiple components, while the programmable gain amplifier helps to reduce noise in the digital output. All in all, this ADC is a great choice for any application that requires analog-to-digital conversion.
