CMOS, ±5 V/+5 V, 4 Ω, Single SPDT Switch (Break-Before-Make Switching Action)
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.
The ADG619-EP support defense and aerospace applications (AQEC standard)Product Highlights

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
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.
