FSA551 - Dual SPST Depletion Mode Audio Switch

General Description

The FSA551 is a high-performance dual single-pole single-throw (SPST x 2) audio switch.

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

Key Features

  • Dual SPST.
  • Depletion Mode Technology.
  • -3 dB Bandwidth: 240 MHz.
  • VCC-OFF: 1.5 V to 3.0 V.
  • VCC-ON: 0 V to 0.2 V.
  • VSW-OFF: -0.3 V to 3 V.
  • VSW-ON: -0.3 V to 3 V.
  • RON: 0.38 Ω Typical.
  • RON Flat: 0.01 Ω (Typical).
  • THD+N: 0.0005% (Typical).
  • Fairchild Green, RoHS Compliant, Halogen Free.
