Data Acquisition - Analog to Digital Converters (ADC): AD7708BR-REEL7 application field and working principle

Analog to Digital Converters (ADCs) are essential components of many electronic circuits, allowing analog signals to be reliably and accurately converted into precise digital representations. The AD7708BR-REEL7 is an integrated ADC that is particularly suited to low resolution, low power applications. It includes an 8-bit Sigma-Delta Analog-to-digital converter (ADC) with a 3-channel multiplexer and on-chip voltage reference. It features low power consumption, high performance and small size.

The AD7708BR-REEL7 is capable of precise conversion of signals into digital data at sampling rates of up to 15 kSamples/sec. It is designed for use in low-resolution signal processing applications, such as thermal and piezoelectric transducers, temperature sensors, active pressure sensors and biometric measurements. It is particularly suitable for applications where precision and accuracy are necessary, as it can provide an 8-bit conversion accuracy of up to 7.5 bits.

The AD7708BR-REEL7 works by using a Sigma-Delta conversion process. This type of conversion uses successive approximation, allowing the input signal to be sampled sequentially until it reaches the required accuracy. The sampled signal is then compared to the reference voltage, and the result is output as a digital signal. The result is an accurate digital representation of the original analog signal.

The AD7708BR-REEL7 also includes additional built-in features such as a multiplexer and a voltage reference. The multiplexer enables multiple signals to be connected to the ADC, allowing for quick and simultaneous sampling of multiple channels. The on-chip voltage reference helps ensure accurate conversion results by providing a stable reference voltage for the ADC. This helps reduce errors and ensure precision in the conversion process.

In summary, the AD7708BR-REEL7 is an ideal choice for low resolution, low power applications where accuracy and precision are essential. It uses a Sigma-Delta conversion process that is accurate and efficient, and it includes a multiplexer and a voltage reference for increased accuracy and flexibility.
