DG3257 Single SPDT Analog Switch

DG3257 Single SPDT Analog Switch

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
Features
  • Ultra-compact 1 mm x 1 mm x 0.35 mm μDFN6 package
  • Low resistance of 5 Ω at 4.2 V
  • -3 dB bandwidth of over 700 MHz
  • -32 dB crosstalk at 240 MHz
  • -33 dB off-isolation
  • Low parasitic capacitance CD(ON) of 9 pF and CS(OFF) of 3 pF
  • RoHS compliant
  • Latch up current of 300 mA per JESD78
  • ESD tolerance > 6 kV (human body model)
  • 1.4 V logic threshold to ensure low voltage TTL/CMOS compatibility
  • Guarantees less than 1 μA of leakage current in the power-down condition
  • Break-before-make switching with a 17 ns turn-on time and an ultra-low 100 ps propagation delay
Applications
