FSA553 - Dual SPST Depletion Audio Switch

General Description

The FSA553 is a high-performance dual single-pole single-throw (SPST x 2) audio switch.

The Depletion 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 Switch.
  • Normally Closed when VCC < 0.2 V.
  • Switches Configurable through Select Pins.
  • VSW: -1.5 V to +1.5 V.
  • RON: 0.4 Ω (Typical).
  • RFLAT < 0.01 Ω (Typical).
  • THD+N: -104 dB (Typical).
  • OIRR: -78 dB (Typical).

FSA553 — Dual SPST Depletion Mode Audio Switch with Negative Swing April 2015 FSA553 Dual SPST Depletion Audio Switch with Negative Swing Features  Dual SPST Depletion Switch  Normally Closed when VCC < 0.2 V  Switches Configurable through Select Pins  VSW: -1.5 V to +1.5 V  RON: 0.4 Ω (Typical)  RFLAT < 0.01 Ω (Typical)  THD+N: -104 dB (Typical)  OIRR: -78 dB (Typical) Description The FSA553 is a high-performance dual single-pole single-throw (SPST x 2) audio switch. The Depletion technology allows the device to conduct signals when there is no VCC available and to isolate signals when VCC is present. During signal conduction, the Depletion gate control allows the FSA553 to achieve excellent THD+N performance while consuming minimal power.
