產(chǎn)品詳情
SSM2143是一款集成式差分放大器，用于接收平衡線路輸入，適合要求對共模噪聲有高抗擾度的音頻應(yīng)用。該器件通過對電阻進(jìn)行激光調(diào)整，使之達(dá)到優(yōu)于0.005%的精度，從而實現(xiàn)典型值為90 dB的共模抑制(CMR)。????????????????????????????????????
該器件的其它特性包括10 V/μs的壓擺率和寬帶寬。在整個音頻頻段內(nèi)，總諧波失真(THD)低于0.004%，即使驅(qū)動低阻抗負(fù)載時也是如此。SSM2143輸入級設(shè)計用于處理高達(dá)+28 dBu的輸入信號（G = 1/2）。雖然該器件主要針對G = 1/2的應(yīng)用，但通過反接+IN/-IN和SENSE/REFERENCE，也可以實現(xiàn)2倍增益。
采用增益為1/2的配置時，SSM2143與平衡線路驅(qū)動器SSM2142可提供全集成式單位增益解決方案，能夠在長電纜上驅(qū)動音頻信號。如需增益G = 1的類似性能器件，請參考SSM2141。
隨著互聯(lián)網(wǎng)的快速發(fā)展，Web應(yīng)用程序的開發(fā)越來越受到重視。而在Java開發(fā)領(lǐng)域，SSM框架（Spring + SpringMVC + MyBatis）已經(jīng)成為非常流行的一種開發(fā)架構(gòu)。SSM框架能夠
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.
Abstract: This application note contains information necessary to interface a nonmultiplexed bus processor to the following Dallas Semiconductor T1 or E1 framers and single chip transceivers (SCTs): DS2141A, DS2143, DS2151, or the DS2153.
