BCT4223 - Dual-SPDT Analog Switch

General Description

The BCT4223 is a high-performance, dual single-pole double-throw (SPDT) analog switch.

Specified over a wide operating power supply voltage range, 1.65V to 4.3V, Targeted applications include battery powered equipment that benefit from ultra low ON-resistance(0.4Ω) and fast switching speeds.

Key Features

  • Low ON Resistance: 0.4-ohms at 4.2V.
  • Wide VCC Range: 1.65V to 4.3V.
  • Rail-to-Rail Signal Range.
  • ON-Resistance Matching: 0.04 Ω (TYP).
  • ON-Resistance Flatness: 0.08Ω (TYP).
  • High Off Isolation: 57dB at 10MHz.
  • 54dB (10MHz) Crosstalk Rejection Reduces Signal Distortion.
  • Break-Before-Make Switching.
  • -3dB Ba.

May, 2008, REV0.0 BCT4223 Low-Voltage, 0.4Ω Dual-SPDT Analog Switch General Description The BCT4223 is a high-performance, dual single-pole double-throw (SPDT) analog switch. Specified over a wide operating power supply voltage range, 1.65V to 4.3V, Targeted applications include battery powered equipment that benefit from ultra low ON-resistance(0.4Ω) and fast switching speeds. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching.
