SGM4157中文资料SPDT 1Ω Analog Switch数据手册SGMICRO规格书

描述 Description

The SGM4157 is a single Low on-resistance (1Ω), fast single-pole double-throw (SPDT) CMOS switch. It is designed for low operating voltage, high current switching of speaker output for cell phone applications. The SGM4157 can handle a balanced microphone/speaker generator in a monophone mode. The device contains a break-before-make (BBM) feature.The control input, IN, tolerates input drive signals up to 5.5V, independent of supply voltage.SGM4157 is available in Green TDFN-2×2-6L package.
