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 www.DataSheet4U.com 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. SPDT 1Ω Analog Switch FEATURES − − − − − − − − − − Voltage Operation : 1. 8 V to 5. 5 V On-Resistance: 0.8Ω (TYP) at 4.5V -3dB Bandwidth: 80 MHz High Off-Isolation: 60dB at 1MHz Rail-to-Rail Operation Low Static Power TTL/CMOS Compatible Break-Before-Make Switching Extended Industrial Temperature Range: –40°C to 85°C Microsize Package PIN CONFIGURATIONS（TOP VIEW） APPLICATIONS Portable Instrumentation Battery-Operated Equipment Computer Peripherals Cell Phones PDAs MP3s SGM4157YD6 NO GND NC 1 2 3 DFN-6 6 5 IN V+ FUNCTION TABLE LOGIC 0 1 NO OFF ON NC ON OFF 4 COM PIN DESCRIPTION NAME NO GND NC COM V+ IN PIN 1 2 3 4 5 6 FUNCTION Normally-open terminal ground Normally-closed terminal Common terminal Power supply Digital control pin to connect the COM terminal to the NO or NC terminals Switches Shown For Logic “0” Input Note: NO, NC and COM terminal may be an input or output.
