The PCM1719E is a special-purpose data acquisition component, used for accurately acquiring, storing and outputting analog signals. This component is typically used in multimedia or audio/video applications, where high-speed data acquisition and conversion are a necessity.

The PCM1719E is capable of two distinct operations: data acquisition and playback. In data acquisition mode, the component uses an input gain stage (IGS) to convert the analog signal into the digital format required for storage and playback. In the playback mode, the component can be used to output the digital signal in the same format as it was received.

The PCM1719E takes advantage of a novel architecture termed as “stacked converter.” In this architecture, the component contains two stacked converters. The analog-to-digital converter (ADC) is used to convert the analog signal into a digital format while the digital-to-analog converter (DAC) is used to output the digital signal. The IGS is the third element of the stack.

The PCM1719E makes use of a high-speed SAR ADC for data acquisition. This ADC is capable of sampling analog signals at a rate of 1 MS/s. The input gain stage (IGS) can be adjusted to achieve the desired signal-to-noise ratio. The ADC also incorporates a harmonic rejection filter to reduce unwanted noise from the incoming signals.

The DAC is capable of outputting signals at a rate of 2 MS/s. The DAC also includes a DC offset control for fine-tuning the playback level and frequency response. The output range of the DAC can be adjusted to suit the application.

The PCM1719E also features an input mux, which is used to select the incoming signal source. The input mux can be used to multiplex different types of audio signals, including microphone, line-in, and USB audio sources.

The PCM1719E is well-suited for a variety of audio/video applications, including multimedia players, audio conferencing, and high-fidelity sound systems. This component is also suitable for applications requiring high-speed data acquisition and conversion. The PCM1719E is a cost-effective solution for applications that require accurate, high-quality data acquisition and playback.
