SINGLE CHIP PC AUDIO SYSTEM

CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO+I2S

92HD93

Features

•

4 Channels (2 stereo DACs and 2 stereo ADCs)

with 24-bit resolution

•

Supports full-duplex stereo audio and simultaneous

VoIP

Provides a mono output

2.1 audio crossover support

Description

The 92HD93 single-chip audio system is a low power

optimized, high fidelity, 4-channel audio codec with

integrated speaker amplifier, capless headphone amplifier,

and low drop out voltage regulator.

电视常识每日新知：软硬屏区分方法

IPS面板最大的特点就是它的两极都在同一个面上，而不象其它液晶模式的电极是在上下两面，立体排列。该技术把液晶分子的排列方式进行了优化，采取水平排列方式，当遇到外界压力时，分子结构向下稍微下陷，但是整体分子还呈水平状。在遇到外力时，硬屏液晶分子结构坚固性和稳定性远远优于软屏!所以不会产生画面失真和影响画面色彩，可以最大程度的保护画面效果不被损害。 IPS硬屏技术是目前世界上最领先的液晶技术。与...[详细]

为什么焊接工匠都爱助焊剂？揭开回流焊接的秘密

在电子制造过程中，回流焊接是最常用的方法之一，它允许在相对短的时间内焊接大量的元件。然而，任何经验丰富的电子工程师都会告诉你，没有助焊剂，高质量的回流焊接是无法完成的。那么，为什么回流焊接时需要使用助焊剂呢？以下几个方面可以解释这一点。首先，助焊剂的主要功能是帮助焊接材料在被焊接表面上均匀分布。焊接是一个涉及熔化金属并使其重新固化的过程。如果金属在固化之前不能均匀分布在被焊接表面上，焊接质...[详细]

HTTP是超文本传输协议的英文缩写，是基于TCP/IP通讯协议之上用来传输HTML和图片文件的应用协议，它是一个应用层面向对象的协议，优点是简捷、快速，适用于分布式超媒体信息系统。 HTTP协议主要工作于B-S架构之上，这个时候浏览器作为HTTP的客户端通过URL向HTTP的服务器（web服务器）发送所有请求，web服务器根据接收到的请求后，向客户端发送响应信息。客户端向服务器请求发送时，需...[详细]
MQTT以太网IO远程模块

MQTT以太网IO模块大部分应该就是采集一些IO口信息，通过网口传输数据。实际上，以太网IO模块除了做TCP server，还可以做TCP Client，除此之外，不但可以高速脉冲计数还可以高速脉冲输出。这个对于在工业现场做一些控制处理，比如控制伺服电机等场景是非常方便的！最重要的，还要数据缓存功能，网络掉线也不怕，数据会自动缓存，恢复网络后会自动补传。 MxxxT 工业远程以太网 I/O ...[详细]
电动汽车的全驱和四驱有什么区别

驱动方式对于车辆来说，并不陌生，根据车辆的驱动方式来说，有前驱，后驱甚至是四轮，而四驱对于新能源汽车可谓是一大买点，在很多新发布的新能源汽车，根据车辆的驱动形式来说，车辆驱动形式里面会有如极速电四驱，双电机4WD、双电机全轮驱动等。对于这些四驱的而言可谓是让人眼花缭乱的，根据车辆来说，新能源全驱动和四驱有什么区别？从驱动的结构上和工作原理上面来说，全驱动是不需要驾驶员对于车辆进行选择操作的...[详细]
对于电动汽车而言，它真的不需要变速箱吗

民用内燃机工作范围约为1000-4000rpm。这就造成了发动机在低转速或者过高的转速区间内，对汽车的加速提供的动能帮助有效，也就是说起步困难，到了高速时再加速困难。解决该问题需要调节发动机的传动比，这就诞生了变速箱。低速起步时采用较大的传动比，高速时采用较小的传动比来保证发动机动力的有效输出。而电动汽车的电机与内燃机在动力输出特性方面有着十分明显的区别。电机的动力输出是转速越低扭矩...[详细]
