Analog-to-digital converters (ADC) are important components of analog circuits and systems, and they are used in a wide variety of applications. AD7266BCPZ-REEL7 is a high performance, low power, low noise, 8-bit, serial analog-to-digital converter from Analog Devices Inc (ADI). It is suitable for applications like industrial process control and precision instrumentation for measurement in the field of communication, automotive, industrial, consumer, and medical. This article will discuss the field of applications and the working principle of the AD7266BCPZ-REEL7.

Field of Applications

The AD7266BCPZ-REEL7 is a low power, low noise 8-bit Analog-to-Digital Converter, which makes it ideal for use in low power and low noise applications. It is ideal for use in sensor and telemetry systems, in monitoring and control applications, in process control and measuring systems, and in medical diagnostics instruments. The AD7266BCPZ-REEL7 is ideal for use in noisy and low power environments, such as for sensing temperature, pressure, and position. In addition, the low power consumption of the AD7266BCPZ-REEL7 makes it ideal for battery-powered systems.

Working Principle

The AD7266BCPZ-REEL7 is a dual, 8-bit serial Analog-to-Digital (A/D) converter. It is designed to allow for digital conversion of an analog input signal with a resolution of up to 8 bits (256 possible values). It operates with a single 5V power supply and its operating temperature range is between -40C and 85C. The AD7266BCPZ-REEL7 includes an on-board clock source and a voltage reference, which eliminates the need for an external clock source and a separate reference voltage.

The AD7266BCPZ-REEL7 supports up to 12 analog inputs. It has an integral, low-noise, low-offset AC amplifier which ensures accurate tracking of the input signal across the full range of input conditions. It offers daisy chain capability, allowing data from multiple converters to be accessed in a single operation by connecting them in series. This provides high performance and flexibility which is valuable in applications with multiple analog inputs.

The AD7266BCPZ-REEL7 can either be used in an 8-bit single-ended mode or a 12-bit mode of operation. In 12-bit mode, each input is sampled and compared to the reference voltage by a successive approximation process. The 8-bit output data is digitalized and converted to a 12-bit output result. This ensures accurate digital conversion with minimal noise and low power consumption.

The Analog Inputs can be AC or DC coupled. The AD7266BCPZ-REEL7 uses pins 5 and 9 to select the coupling type. When pin 9 is low, AC coupling is activated and the input signal is applied to the AC amplifier, which dynamically compensates for the offset. When pin 5 is high, DC coupling is activated, the input signal is applied directly to the 8-bit ADC.

Conclusion

The AD7266BCPZ-REEL7 is a high performance, low power, low noise, 8-bit, serial analog-to-digital converter from Analog Devices Inc (ADI), which makes it ideal for applications where low power and low noise are important. It has a wide range of applications, such as for monitoring and control applications, in process control and measuring systems, and in medical diagnostics instruments. It offers a single supply, low noise and low power operation, and it supports up to 12 analog inputs. The AD7266BCPZ-REEL7 can either be used in 8-bit single-ended mode or a 12-bit mode of operation. This provides high performance and flexibility which is valuable in applications with multiple analog inputs.
