ADG620:  CMOS, ±5 V/+5 V, 4 Ω, Single SPDT Switch (Make-Before-Break Action)

Product Details


The ADG619/ADG620 are monolithic, CMOS single-pole double-throw (SPDT) switches. Each switch conducts equally well in both directions when the device is on.

The ADG619/ADG620 offer a low on resistance of 4 Ω, which is matched to within 0.7 Ω between channels. These switches also provide low power dissipation, yet result in high switching speeds. The ADG619 exhibits break-before-make switching action, thus preventing momentary shorting when switching channels. The ADG620 exhibits make-before-break action.

The ADG619/ADG620 are available in an 8-lead SOT-23 and an 8-lead MSOP.

Product Highlights

  • Low on resistance (RON): 4 Ω typical.
  • Dual ±2.7 V to ±5.5 V or single 2.7 V to 5.5 V supplies.
  • Low power dissipation.
  • Fast tON/tOFF.
  • Tiny, 8-lead SOT-23 and 8-lead MSOP.
