FSA550 - 4PST Depletion Mode Isolation Switch

General Description

The FSA550 is a high-performance four-pole singlethrow (4PST) normally closed Depletion-Mode isolation switch.

The Depletion Mode technology allows the device to conduct signals when there is no VCC available and to isolate the signals when VCC is present.

Key Features

  • 4PST (NC).
  • Depletion Mode MOSFETs.
  • Audio Frequency Range.
  • VCC(OFF): 1.6 V to 3.0 V.
  • RON: 0.8 Ω Typical.
  • RON Flat: 0.01 Ω Typical.
  • THD+N: 0.002% Typical.
  • Eco Status: Fairchild Green, RoHS Compliant, Halogen Free.
