# PCM1737E Product Series Introduction

## 1. Overview
The PCM1737E product series is a cutting - edge offering in the field of audio digital - to - analog converters (DACs). Developed with state - of - the - art technology, these DACs are designed to meet the high - performance requirements of a wide range of audio applications. Whether it's in consumer audio devices, professional audio equipment, or automotive audio systems, the PCM1737E series stands out for its exceptional sound quality, advanced features, and reliable performance.

## 2. Key Features

### 2.1 High - Resolution Audio Conversion
- The PCM1737E series supports high - resolution audio formats, including up to 24 - bit/192kHz sampling rates. This high - resolution capability allows for the reproduction of audio with incredible detail, capturing every nuance of the original recording. Whether it's the delicate notes of a classical piano piece or the powerful bass in a modern electronic track, the DAC can accurately convert the digital audio data into an analog signal with high fidelity.
- It uses advanced digital filtering algorithms to minimize noise and distortion during the conversion process. This ensures that the output audio is clean, clear, and free from artifacts, providing an immersive listening experience.

### 2.2 Low - Noise and Low - Distortion Performance
- With extremely low noise floor and low total harmonic distortion plus noise (THD+N), the PCM1737E series offers pristine audio quality. The low noise performance means that there is minimal background hiss or interference in the audio output, allowing the listener to focus on the pure sound of the music.
- The low distortion ensures that the audio signal remains faithful to the original, without introducing any unwanted coloration or distortion. This is especially important in high - end audio systems where accuracy and purity of sound are paramount.

### 2.3 Flexible Input Interface
- The DACs in the PCM1737E series come with a flexible input interface that supports a variety of digital audio input formats, such as I2S, left - justified, and right - justified formats. This flexibility makes it easy to integrate the PCM1737E into different audio systems, whether they are based on microcontrollers, digital signal processors (DSPs), or other audio - processing chips.
- It also has built - in input buffering and synchronization circuits, which can handle different input clock frequencies and data rates, ensuring stable and reliable operation in various application scenarios.

### 2.4 Integrated Output Stage
- The PCM1737E series features an integrated output stage that can directly drive headphones or line - level audio loads. This eliminates the need for an external amplifier in some applications, reducing the overall component count and cost of the audio system.
- The output stage is designed to provide a high - quality analog output signal with sufficient drive capability, ensuring that the audio can be heard clearly and loudly without any loss of quality.

### 2.5 Power Management Features
- These DACs are equipped with power management features that help to reduce power consumption and extend battery life in portable audio devices. They support different power - saving modes, such as standby and shutdown modes, which can be controlled through the digital interface.
- The low - power operation also helps to reduce heat generation, which is beneficial for the long - term reliability and stability of the audio system.

## 3. Applications

### 3.1 Consumer Audio Devices
- In home audio systems, such as CD players, digital audio players, and soundbars, the PCM1737E series can significantly enhance the audio quality. It can reproduce the music with high fidelity, providing a more immersive and enjoyable listening experience for the users.
