Very Low On Resistance: 0.5 typ. pole, single-throw (SPST) switches. These switches are designed 2. On Resistance Flatness (RFLAT(ON)): 0.15 typ. on an advanced submicron process that provides low power 3. Automotive Temperature Range: 40C to +125C. dissipation, yet gives high switching speed, low on resistance, 4. Current Carrying Capability: 200 mA. and low leakage currents. 5. Low Power Dissipation. CMOS construction ensures low power dissipation. The ADG821/ADG822/ADG823 are designed to operate from 6. 8-Lead MSOP. 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. Rev.
