Data Acquisition has had a pivotal role since the world started its process of development, playing a major role in the advancement of various fields like communication and industries. In general, data can be obtained from either digital or analog components. If a component involves an analog system, then it needs to be converted into an appropriate digital form for purposes like further processing and storage. The AD9633BCPZRL7-105, an Analog to Digital Converter (ADC), is a tool used for carrying out this task.

The AD9633BCPZRL7-105 is a low Power and wide voltage range pulse density modulator (PDM) and ADC converter, capable of providing quality performance in both low-voltage and high-speed operation. It helps in the conversion of variable analog signals into digital signals that can then be adapted to provide direction to a computer. The chip uses a dual-channel PDM design that enables it to offer mute and disable features, along with controlled response performance. As it is available in a package of 10mmX9mm, Featuring an Overall height of 1.8mm, the chip is compact and ideal to be used in portable devices.

The chips primary function of providing analog to digital conversion is done by utilizing a differential-input architecture. The chip has an on-chip sample-and-hold circuitry that facilitates the acquisition of analog signals for the application of the delta-sigma modulator at the operational rate. A second-order modulator present on the chip facilitates the application of a user-selectable gain range from +6dB to -72dB by using the reference voltage that is set using one of the two 24-bit ports- it can be a user-defined input programmed using the I2C master port. The output of the modulator is then fed to a decimation filter for the purpose of denoising.

The chip has a wide range of applications, ranging from power line communications to portable audio systems due to its low-power and capability to down-convert high sample-rate data into a low-rate DAC. It can be utilized in audio codec applications since the low-voltage differential signaling (LVDS)-compatible outputs allow quick sampling of an audio signal with less noise. It can also be used in cellular baseband RF systems leveraging the on-chip PDM with the modulator inputs allowing the simultaneous coverage of multiple application bandwidth. The chip also has a better power optimization technique prescribed by its Internal Current mirrors, enabling high dynamic performance in a low-voltage range.

The utility of the AD9633BCPZRL7-105 is also used in telecommunication systems such as Digital Enhanced Cordless Telecommunications (DECT) and digital cellular systems making use of the frequency modulation and a complete tune device which operates using the methods of I-square-root law. With its efficient analog to digital conversion, it enables the devices to deliver high performance and superior audio delivery using very small power acting as a key enabling tool for the low-power portable audio devices.

In addition, the digital output spectrum produced allows users to maintain better control over the audio product produced. The chip also has a noise power spectrum compression feature which further enhances the audio quality produced. Furthermore, the versatile On-Chip features of the chip can easily be used by audio designers to make use of a low-voltage differential signaling (LVDS) compatible output allowing rapid sampling of the audio signal, alongside providing a low-noise audio output.

The AD9633BCPZRL7-105 has helped the industry, delivery superior quality audio with excellent noise power spectrum compression in less time and power enabling the portable audio devices to be an integral part of our life. This chip has enabled the industry to leverage a spectrum of benefits from efficient analog to digital conversion, along with usage in multiple application bandwidths in efficient and easier ways.
