The ADG1208 and ADG1209 are monolithic, iCMOS® analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG1208 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1, and A2. The ADG1209 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 enable or disable the device. When disabled, all channels are switched off. When on, each channel conducts equally well in both directions and has an input signal range that extends to the supplies.
The iCMOS (industrial CMOS) modular manufacturing process combines high voltage CMOS (complementary metal-oxide semiconductor) 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 devices 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 capacitance and exceptionally low charge injection of these multiplexers make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. There is minimum charge injection over the entire signal range of the device. iCMOS construction also ensures ultralow power dissipation, making the ds ideally suited for portable and battery-powered instruments.

Markets and Technologies
Product Lifecycle Production
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.
Evaluation Kits (1)
The EVAL-16TSSOPEBZ evaluation board evaluates 16-lead TSSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-16TSSOPEBZ to secure a 16-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.
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.
