The PCM1716E is a special-purpose device designed as an eight-channel, high-precision analog-to-digital (ADC) converter. It is designed for applications requiring low power consumption and a minimal number of on-chip external components, making it an ideal product for embedded systems. It is used in professional audio production, medical imaging, and car audio systems, as well as robotics, military, and other sensitive applications such as seismic data acquisition.

The PCM1716E is a 10-bit, 24-bit successive approximation ADC that operates from a 5 V power supply, and provides an ENOB of up to 9.5 bits. It is a high dynamic range ADC, with excellent linearity and total harmonic distortion (THD) of typically 75 dB. It features a high-precision analog reference, and built-in digital logic which allows its operation without the need for an external controller.

How does it work? The PCM1716E has an input section that amplifies and filters the input signal prior to the analog-to-digital conversion process. This allows for improved SNR and dynamic range for the output digital data. It also has an output section, which consists of an 8-bit digital-to-analog converter (DAC). This DAC provides the output code, which is sent out in response to the incoming signal.

The PCM1716E also features an on-chip arbitration logic block, which handles timing of the ADCs and DACs. This allows multiple ADCs to be chained together, and allows the simultaneous conversion of up to eight 8-bit codes. This allows you to get multiple readings in a single conversion process, reducing power consumption and improving accuracy.

The PCM1716E is suitable for applications requiring very accurate analog-to-digital conversion with low power consumption. Its input section provides excellent noise rejection and dynamic range, making it suitable for use in low-signal-to-noise applications. The 8-bit DAC ensures accurate output codes from the ADC, and the on-chip arbitration logic block allows for asynchronous operation of multiple ADCs.

In conclusion, the PCM1716E is a highly versatile and reliable digital-to-analog converter suitable for applications requiring low power consumption and excellent performance. Its integrated logic allows for high speed operation, and easy integration into existing systems. Its on-chip arbitration logic and 8-bit DAC also allow for simplified system design, improving performance and accuracy.
