The ADG408 is a monolithic CMOS analog multiplexer comprising 8 single channels. The ADG408 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. An EN input is used to enable or disable the device. When disabled, all channels are switched OFF.
The ADG408 is designed on an enhanced LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance. Each channel conducts equally well in both directions when ON and has an input signal range which extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit break before make switching action preventing momentary shorting when switching channels. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.

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.
Features & Benefits
- 16 lead TSSOP evaluation board
- Clamp to allow the main device to be changed easily
- Gold pin connectors to allow the addition of passive components
- SMB connectors for the input/output of signals
- Additional space on board to allow for prototyping
Tools & Simulations
ADG408 SPICE Macro Models
ADIsimPE, which is powered by SIMetrix/SIMPLIS, is a circuit simulation suite optimized for the design and development of analog and mixed signal circuits. SIMetrix mode is ideal for the simulation of general non-switching circuits. It provides full Pspice compatibility for use with industry-standard SPICE models. SIMPLIS (SIMulation Piecewise-Linear System) mode simulates the operation of switching circuits with vastly improved robustness, speed, and accuracy compared to standard SPICE. It is particularly useful for switching power supply, PLLs, and ADC/DAC applications.
Product Selection Guide (1)
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
