The topic of this article is 12008/70086 application, field and working principle. This article is mainly about the applications, fields and working principles of 12008/70086. This article is classified under Miscellaneous.

12008/70086 is a sigma-delta modulator, which usually consists of the quantizer, digital loop filter and a switch. This modulator can perform high precision analog signal quantization, low power analog signal processing, and many other functions. Additionally, this modulator has become popular in various application fields since it has low power consumption and low cost.

The common application fields of 12008/70086 are in digital audio signal process, sensor signal processing, data acquisition, data transmission and switching field. In digital audio signal process, 12008/70086 modulator is particularly useful for the analog to digital conversion of audio signals, since this modulator has great performance in high precision digital signal processing, as well as being able to achieve low cost and low power consumption.

In sensor signal processing, it is able to provide high precision digitalized signal for those sensors, such as medical and measuring sensors, which can produce low level and tiny variable signals. Therefore, the analysis and digitalization of these signals can be done with great accuracy without introducing any more noise, especially for the medical applications, such as EEG monitoring, where the accuracy of the signal is extremely critical.

The working principle of 12008/70086 modulators is built on the basic concept of sigma-delta modulator which consists of two parts: quantizer and noise-shaper. In this modulator, the input signal is usually sampled by an ADC after a low-pass filter, and then quantized by a quantizer, transforming it to a digital signal. This analog-digital converter has the benefit of high accuracy, since the quantizer is designed to be very accurate and can minimize the distortion of signals caused by rounding errors. Besides, the noise-shaper constantly shapes the low frequency noise, compensating the quantization errors.

In conclusion, 12008/70086 modulator is a versatile and innovative sigma-delta modulator which performs many analog-to-digital functions. Generally, it is used in digital audio signal processing, sensor signal processing, data acquisition, data transmission and switching field. Additionally, it has low power consumption and low cost due to its efficient working principle which contains separate quantizer and noise-shaper enabling greater signal accuracy and less noise.
