General Description
ADG821 General Description
The ADG821, ADG822, and ADG823 are monolithic CMOS SPST (single pole, single throw) 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, and 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, and ADG823 contain two independent SPST switches. The ADG821and 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, and ADG823 are available in an 8-lead MSOP package.

NOTES
1 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time.
2 Overvoltages at IN, S, or D will be clamped by internal diodes. Current should be limited to the maximum ratings given.
