Targeted applications include battery powered equipment that benefit from ultra low ON-resistance (0.4Ω) and fast switching speeds.       SGM2268 features guaranteed on-resistance matching (0.04Ω TYP) between switches and guaranteed on- resistance flatness over the signal range (0.08Ω TYP), as well as high Off-Isolation and low crosstalk. This ensures excellent linearity and low distortion when switching audio signals.       The SGM2268 is a committed dual single-pole/double -throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer.       SGM2268 is available in Pb-free WQFN-10 package.产品特性     Voltage Operation : +1.8V to +4.2V    Ultra Low On-Resistance: 0.4Ω (TYP) at +4.2V    On-Resistance Matching : 0.04Ω (TYP)    On-Resistance Flatness: 0.08Ω (TYP)    -3 dB Bandwidth: 40MHz    High Off-Isolation: -78dB at 100KHz    Low Crosstalk: -103dB at 100KHz    Rail-to-Rail Input and Output Operation    TTL/CMOS Compatible    Break-Before-Make Switching    Extended Industrial Temperature Range:    –40°C to +85°C    Lead (Pb) Free WQFN-10 Package应用领域 Portable InstrumentationBattery-Operated EquipmentComputer PeripheralsSpeaker and Earphone SwitchingMedical EquipmentAudio and Video Switching
