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.

Evaluation Kits 1
EVAL-8MSOP
Evaluation Board for 8 lead MSOP Devices in the Switch/Mux Portfolio
Product Detail
The EVAL-8MSOPEBZ is the evaluation board for the 8 lead MSOP devices in the switch/mux portfolio which are to be purchased separately. A clamp is supplied with the board so that the device can be secured to the board without the need for soldering. This makes the board reusable for multiple devices.
The device can be clamped or soldered to the center of the evaluation board. Each pin of the device is broke out to a link that can be set to either VDD or GND and a wire screw terminal is provided to supply VDD and GND. SMB connectors are on the board allow for additional external signals to be supplied to the device. In addition, there is space at the top of the board available for prototyping.
Full specifications of the device under test are available in the product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
