SGM Ω, High Speed, Low Voltage Analog Switch/Multiplexer

Transcription

1 nalog Switch/Multiplexer GENERL DESCRIPTION The SGM84782 is high-speed, low-voltage, low on-resistance, CMOS analog multiplexer/switch that configured as two 4-channel multiplexers. It operates from a single +1.8V to +4.2V power supply. Targeted applications include battery powered equipment that benefit from low R ON (4) and fast switching speeds (t ON = 17ns, t OFF = 9ns). The SGM84782 can handle rail-to-rail analog signals and is available in Green TQFN L and TSSOP-16 packages.

Functional operation of the device at these or any other conditions beyond those indicated in the operational section of the specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. ESD SENSITIVITY CUTION This integrated circuit can be damaged by ESD if you don t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. DISCLIMER reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time.
