PCM1681PWPRG4

The PCM1681PWPRG4 is an integrated special-purpose data acquisition device that combines clock and data acquisition functions. A typical solution integrates the system processor, peripheral audio amplifiers, clock and analog data acquisition interfaces, enabling system clock and data acquisition functions at the same time. It is suitable for mass storage, multimedia, computer audio and other applications.

The PCM1681PWPRG4 includes an embedded analog-to-digital converter (ADC) with a resolution of 10 bits, four-terminal (4-wired) data acquisition interface with a sample rate of up to 384 kHz and a low-voltage differential signaling (LVDS) interface. The combination of these interfaces enables high speed and low power data acquisition. In addition, there is an integrated clock input/output (CICON), allowing for advanced clock schedulability. The clock is allocated to a specific channel and is adjustable from 8 kHz to 384 kHz. It is designed to provide a low-cost, space-saving solution for audio device applications.

The working principle of the PCM1681PWPRG4 is analogous to a digital audio recorder. The device first acquires analog input signals, processes them through an ADC, and then stores them in a ROM. The ROM\'s stored data are then read out from the ROM by the system processor, allowing for the I/O stream processing. The output of the system processor can then be written back to the ADC, allowing for the generation of an output signal corresponding to the input signal. The clock input/output (CICON) of the PCM1681PWPRG4can be used to sync the input/output data, providing a low-cost solution for audio device applications.

In terms of its application fields, the PCM1681PWPRG4 can be used in data acquisition, multimedia, audio interface and other applications. For example, it can be used in computer audio applications, such as digital audio recorders, digital audio players and other applications. It can also be used in the acquisition of data from medical applications, such as a medical instrument monitoring system, which specifies the input/output data for each type of medical equipment. In addition, it can also be used for the acquisition of data from automotive and industrial applications.

The PCM1681PWPRG4 is an ideal solution for applications requiring both analog-to-digital conversion and clock functions. Its integrated design enables both clock and data acquisition, providing low power data acquisition and clock synchronization. In addition, its low cost and space-saving design make it an excellent choice for audio device applications such as computer audio recorders, players and monitors.
