【产品】可自动识别CTIA/OMTP的耳机接地极开关,接地阻抗低至70mΩ
SGM2549是SGMICRO公司推出的一款耳机接地极开关。其具有紧凑的尺寸,接地阻抗可低至70mΩ,左右声道串扰(1kHz/32Ω)为-52dB,FM频段插入损耗为-0.5dB。SGM2549能够自动识别CTIA、OMTP及无麦耳机的连接,适合耳麦连接应用,以及那些非耳麦的应用,如:音频口加密狗,自拍杆,线控拍照按钮等。
由于CTIA和OMTP定义中的回流地线触点和MIC触点位置不同,会导致配错耳麦后耳机的声音几乎听不到,同时麦克风里面只有耳机放出的声音。而SGM2549耳机接地极开关可自动识别是哪种耳麦,并利用其内部开关正确地完成连接,解决了设备和耳麦不能匹配的问题。其静态电流为3.4μA,当识别出麦克风时电流可降至1.4μA。其CTIA和OMTP中定义的GND和MIC位置如下图所示:
SGM2549耳机接地极开关既可以在驱动侧使用,也可以在耳机侧使用,两侧同时使用也可正常识别和正确接通。SGM2549耳机接地极开关支持从GM1/GM2上取电,也可通过L/R端信号整流供电,无需单独VCC电源供电。其驱动侧和耳机侧的应用电路如图2所示。
SGM2549耳机接地极开关的工作温度范围为-40℃~+85℃,结温范围为-40℃~+125℃。该产品采用了绿色的SOT-23-6和UTDFN-1.5×2-6L封装。可用于手机/平板电脑/电脑/媒体播放器,耳机/耳机插头键/耳机插头按钮领域。

【选型】圣邦微耳机接地极开关SGM2549助力对讲机项目,自动识别CTIA、OMTP端口开关
因为耳机接口回流地线触点和MIC触点位置不同,可能导致一个对讲机不能同时兼容CTIA(美国)和OMTP(欧洲)两个不同的标准耳机头。使用SGMICRO的耳机接地极开关SGM2549,则可以自动识别GND和MIC,并把相应的通道打开,实现两个不同标准的兼容,解决了设备和耳麦不能匹配的问题。
