# PCM1702P Product Series Introduction

## 1. Overview
The PCM1702P is a remarkable product series within the realm of audio digital - to - analog converters (DACs). Developed with cutting - edge technology, it is designed to meet the high - quality audio conversion needs of a wide range of applications. Whether it's in consumer audio devices, professional audio equipment, or industrial audio systems, the PCM1702P stands out for its excellent performance and reliability.

## 2. Key Features

### High - Resolution Audio Conversion
- The PCM1702P offers high - resolution digital - to - analog conversion capabilities. It can handle high - bit - rate audio signals, typically supporting up to 24 - bit audio data. This high - bit depth allows for a much wider dynamic range and more accurate representation of the original audio signal, resulting in rich, detailed, and immersive sound quality. For example, in a high - end home audio system, it can reproduce the subtle nuances of a musical performance, from the softest whispers of a singer to the thunderous crashes of a drum kit.

### Low Distortion
- One of the most significant features of the PCM1702P is its extremely low distortion characteristics. It has a very low total harmonic distortion plus noise (THD+N) figure. This means that the converted analog audio signal closely resembles the original digital input, with minimal added noise and distortion. In a professional recording studio environment, low distortion is crucial for accurate monitoring and mixing, as it ensures that the audio engineers are working with a pure and unadulterated signal.

### Multiple Input Formats
- The product series supports a variety of digital input formats. It can accept serial data in different standards, such as left - justified, right - justified, and I²S formats. This flexibility makes it easy to integrate the PCM1702P into different audio systems, regardless of the existing digital audio interface used. For instance, in a multimedia device that may receive audio data from different sources with varying formats, the PCM1702P can adapt and convert the data effectively.

### On - Chip Filters
- The PCM1702P comes with on - chip digital filters. These filters are designed to optimize the audio signal during the conversion process. They can remove unwanted high - frequency noise and artifacts that may be present in the digital input, resulting in a cleaner and more natural - sounding analog output. The on - chip filters also reduce the need for external filtering components, simplifying the overall circuit design and reducing costs.

## 3. Technical Specifications

### Sampling Rate
- The PCM1702P supports a wide range of sampling rates, typically from 8 kHz to 96 kHz. This wide sampling rate range allows it to be used in various audio applications, from low - bit - rate voice communication systems to high - fidelity audio playback systems. For example, in a mobile phone, a lower sampling rate may be sufficient for voice calls, while in a high - end music player, a higher sampling rate can be used to reproduce the full spectrum of audio frequencies.

### Power Supply
- It operates on a relatively standard power supply voltage range. Usually, it can work with a single +5V power supply, which simplifies the power management design in the audio system. This makes it suitable for use in battery - powered devices as well as in traditional AC - powered audio equipment.

### Output Voltage Range
- The analog output voltage range of the PCM1702P is designed to be compatible with most audio amplifier circuits. It provides a sufficient output voltage swing to drive external audio amplifiers directly, eliminating the need for additional voltage - boosting stages in many cases.
