The ADG1408/ADG1409 are monolithic iCMOS® analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG1408 switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2. The ADG1409 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines, A0 and A1. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched off.
The industrial CMOS (iCMOS) modular manufacturing process combines high voltage complementary metal-oxide semiconductor (CMOS) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no other generation of high voltage parts has been able to achieve. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.
The ultralow on resistance and on resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications where low distortion is critical. iCMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.

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.
A 16-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K16 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.
Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
