SGM4157

SGM4157 GENERAL 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/ringtone 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 a DFN-6 package.
