series introduction
# PCM1748E Product Series Introduction
## 1. Overview
The PCM1748E product series is a remarkable offering in the field of audio digital - to - analog converters (DACs). Developed with cutting - edge technology, it is designed to meet the high - end audio requirements of various applications, from consumer audio devices to professional audio systems. This series combines excellent audio performance, advanced features, and high - quality construction to deliver an immersive and accurate audio experience.
## 2. Key Features
### 2.1 High - Resolution Audio Conversion
- The PCM1748E supports high - resolution audio formats, including up to 24 - bit/192kHz sampling rates. This high - resolution capability allows for the reproduction of audio with exceptional clarity, detail, and dynamic range. It can capture the subtlest nuances in music, such as the delicate plucking of a guitar string or the softest vocal whisper, providing listeners with a more realistic and engaging audio experience.
### 2.2 Low Distortion and Noise
- With extremely low total harmonic distortion plus noise (THD+N) figures, the PCM1748E ensures that the audio output is as pure as possible. Low distortion means that the original audio signal is reproduced accurately without introducing unwanted artifacts or coloration. The low noise floor further enhances the audio quality, allowing for a clean and quiet background, especially during passages of soft music.
### 2.3 Advanced Digital Filtering
- The series is equipped with advanced digital filtering algorithms. These filters can be configured to optimize the audio output for different types of audio content and listening preferences. For example, they can be adjusted to provide a more natural sound for classical music or a more punchy and energetic sound for modern pop and rock. The digital filters also help in reducing aliasing and imaging errors, resulting in a more precise and well - defined audio stage.
### 2.4 Multiple Input Interfaces
- The PCM1748E offers multiple input interfaces, including I2S, left - justified, and right - justified serial data formats. This flexibility allows it to be easily integrated into a wide range of audio systems, whether they are based on microcontrollers, digital signal processors (DSPs), or other audio - processing devices. It can also support different data transfer rates, making it suitable for both low - cost and high - performance applications.
### 2.5 Power Management
- The product series features efficient power management capabilities. It has a low - power standby mode, which helps in reducing power consumption when the device is not in use. This is particularly important for battery - powered audio devices, as it extends the battery life. Additionally, the power - on and power - off sequences are carefully designed to minimize audible clicks and pops, ensuring a smooth and seamless audio experience.
