ADG823:  <1 Ω, Low Voltage (1.8 V - 5.5 V) Dual SPST Switches

Product Details

The ADG821/ADG822/ADG823 are monolithic CMOS single-pole, single-throw (SPST) switches. These switches are designed on an advanced submicron process that provides low power dissipation, yet gives high switching speed, low on resistance, and low leakage currents. The ADG821/ADG822/ADG823 are designed to operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments.

Each switch of the ADG821/ADG822/ADG823 conducts equally well in both directions when on. The ADG821/ ADG822/ADG823 contain two independent SPST switches. The ADG821 and ADG822 differ only in that both switches are normally open and normally closed, respectively. In the ADG823, Switch 1 is normally open and Switch 2 is normally closed. The ADG823 exhibits break-before-make switching action.

The ADG821/ADG822/ADG823 are available in an 8-lead MSOP.
