The PCM1604PTR is a special purpose digital-to-analog and analog-to-digital converter designed for applications requiring true single-ended operation. It therefore finds use in a variety of data acquisition, digital signal processing and audio applications. Its analog output and input can range from single-ended ground referenced to differential.

The PCM1604PTR offer excellent quality, performance and cost-effectiveness to meet the need of today\'s demanding audio applications. Its operating range includes differential input and output, temperature compensated offset and gain errors, low power consumption, excellent signal-to-noise plus distortion, and the flexibility of low voltage operation in a variety of power up / power down configurations.

The PCM1604PTR application fields include data acquisition and signal processing, power line interfacing, analog-to-digital and digital-to-analog conversion, audio interface applications, digital signal processors, and digital-to-analog audio systems.

The PCM1604PTR is a high precision analog-to-digital (A/D) and digital-to-analog (D/A) converter. It is designed to provide 16-bit accuracy in both digital-to-analog and analog-to-digital conversion. The ADC is a custom ultra-high-speed converter based on a differential switched capacitor architecture. The digital encoder provides digitally controlled, power-saving gain and offset correction signals to minimize boost and lag errors. The on-chip high-performance DAC provides low output noise.

The PCM1604PTR supports a wide input voltage range, from single-ended ground referenced to differential signals, and features excellent dynamic performance. To improve accuracy and reduce glitches due to charge injection, differential input signals are converted to single-ended signals by an input buffer before they enter the ADC interface. The ADC inputs also support an optional reference input.

The PCM1604PTR works with a three-phase data flow in a standard PCM digital audio interface (PCMDAI). In this way, the PCMDAI enables digital audio conversion to analog audio with low power consumption, low noise and distortion, and high dynamic range. The PCMDAI supports single-ended unbalanced and differential balanced audio connections, providing jitter-free audio when properly connected.

The PCMDAI provides a data interface to both standard digital audio and PCM1604PTR-compatible digital audio media formats, such as CD, DSD, and other formats requiring 16-bit resolution. The PCDAI also provides access to a variety of digital audio formats, such as WAV, AIFF, FLAC, MP3, and OGG.

The PCM1604PTR is designed to offer excellent performance in audio applications, with its specially designed components and architecture. The PCM1604PTR features two on-chip voltage regulators and a high-performance DAC with excellent signal-to-noise performance. The ADC offers low power consumption, low distortion and low noise, while the DAC provides low latency with high-quality audio.

The PCM1604PTR also features a hardware reset function to ensure stability under varying temperatures and load changes. This ensures that the PCM1604PTR is optimized for maximum performance in audio applications.

In summary, the PCM1604PTR is a versatile digital-to-analog and analog-to-digital converter designed for applications requiring true single-ended operation. It offers excellent quality, performance and cost-effectiveness to meet the needs of today\'s demanding audio applications while operating within a wide input voltage range. The PCM1604PTR also features two on-chip voltage regulators and a high-performance DAC with excellent signal-to-noise performance, low power consumption, low distortion and low noise, and a hardware reset function.
