The DG3257 single SPDT analog switch by Vishay Siliconix offers -3 dB bandwidth of 700 MHz and power down protection in their first ultra-compact µDFN6 package. The DG3257 is ideal for analog and digital signal switching in portable consumer and medical devices, and achieves low resistance of 5 Ω at 4.2 V while delivering improved high bandwidth, reduced parasitic capacitance, and a power-down protection feature.
- To save valuable PCB space, the device is 29% smaller and 36% thinner than switches in the mQFN6
- 400 MHz higher bandwidth than previous generation devices
- 10 dB improvement in crosstalk over competing solutions
- Fabricated with a high density sub-micron CMOS process to deliver 50% lower parasitic capacitance
- Handles bidirectional signal flow with minimal distortion and can be powered directly from a one-cell Li-ion battery
