SSM2143是一款集成式差分放大器，用于接收平衡线路输入，适合要求对共模噪声有高抗扰度的音频应用。该器件通过对电阻进行激光调整，使之达到优于0.005%的精度，从而实现典型值为90 dB的共模抑制(CMR)。
该器件的其它特性包括10 V/µs的压摆率和宽带宽。在整个音频频段内，总谐波失真(THD)低于0.004%，即使驱动低阻抗负载时也是如此。SSM2143输入级设计用于处理高达+28 dBu的输入信号（G = 1/2）。虽然该器件主要针对G = 1/2的应用，但通过反接+IN/-IN和SENSE/REFERENCE，也可以实现2倍增益。
采用增益为1/2的配置时，SSM2143与平衡线路驱动器SSM2142可提供全集成式单位增益解决方案，能够在长电缆上驱动音频信号。如需增益G = 1的类似性能器件，请参考SSM2141。
随着互联网的快速发展，Web应用程序的开发越来越受到重视。而在Java开发领域，SSM框架（Spring + SpringMVC + MyBatis）已经成为非常流行的一种开发架构。SSM框架能够
Abstract: Application Note 306 provides the design requirements for implementing a three channel drop and insert application using the Dallas Semiconductor/Maxim DS2141A T1 framer or DS2143 E1 framer.
Abstract: This application note describes how the DS2141A, DS2143, DS2151, and DS2153 interface to the Siemens PEB2045. This note also shows waveforms and timing diagrams of different pins that are used for interfacing to the PEB2045.
