DG9421EDV-T1-GE3

The DG9421E and DG9422E are monolithic single-pole-single-throw (SPST) analog switches. The DG9421E has a normally closed function. The DG9422E has a normally open function. Processed with high density BiCMOS technology, the parts achieve low resistance, fast switching speed, low power dissipation, high -3dB bandwidth, and low voltage logic control threshold. The DG9421E and DG9422E operate on single and dual supplies. Single supply voltage ranges from +3V to +16V while dual supply operation is recommended with ± 3V to ± 8V. Each switch conducts equally well in both direction when on, and blocks input voltages up to the supply levels when off. The low and flat on resistance over the full input signal voltage range brings excellent linearity, reduces insertion loss and signal distortion, makes them ideal for data acquisition and programmable gain control applications. These switch characters also make them ideal fit for audio signal switch and reed relay replacement. Operation temperature is specified from -40 °C to +85 °C. The DG9421E and DG9422E are available in 6 lead TSSOP packages.
