CR7C-36DB-4E(72) is an analog to digital converter (ADC) that can convert analog input signals into digital output signals. Specifically, it is a two-channel, 12-bit resolution, 7-bit resolution and 4-bit resolution sigma-delta- ADC with oversampling ratio support from 2 to 72 times. In this article, we will talk about its application field and the working principle of this ADC.

The CR7C-36DB-4E(72) ADC is suitable for many audio circuits, because of its excellent noise resistant capabilities. Furthermore, this ADC is also suitable for use in telecommunications, medical, industrial and automotive applications. For example, it can be used in automotive ECU circuits, digital camera modules and audio processing systems due to its low power consumption and the high level of signal accuracy it provides.

The working principle of the CR7C-36DB-4E(72) ADC is based on interpolation and sigma-delta over sampling. In order for the ADC to convert analog signals into digital signals, it first converts analog signals into proportional signals using interpolation. With the help of the sigma-delta modulator, it then samples the proportional signals at a rate much higher than the analog signal. This means that the ADC can sample the same amount of information from the analog signal without the need for a longer sampling period.

The interpolation process helps to reduce errors during the interpolation process, and the output resolution remains 12-bit or 7-bit depending upon the oversampling ratio. For example, if the oversampling ratio is set to 36, then there will be a 12-bit resolution. For 4-bit resolution, the oversampling ratio needs to be 72.

The CR7C-36DB-4E(72) ADC is also able to process digital audio formats such as WAV and FLAC due to its oversampling ratio support. In addition, this ADC supports oversampling rates up to 96 kHz which helps to improve the dynamic range of the ADC and produce better sound quality. The ADC also has built-in dynamic range and distortion control features which reduce noise and improve signal linearity.

Overall, the CR7C-36DB-4E(72) ADC is an ideal choice for applications that require high-resolution signal conversion with low power consumption. The ADC is suitable for a wide range of applications, including medical, industrial, automotive, and audio applications, due to its low power and high signal accuracy. Additionally, the ADC offers a wide range of oversampling rates which helps to improve the dynamic range of the ADC and produce better sound quality.
