The ADG1438 and ADG1439 are CMOS analog matrix switches with a serially controlled 3-wire interface. The ADG1438 is an 8-channel matrix switch, and the ADG1439 is a dual 4-channel matrix switch.

The ADG1438/ADG1439 use a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. The output of the shift register, SDO, enables a number of the ADG1438/ADG1439 devices to be daisy-chained. On power-up, the internal shift register contains all zeros, and all switches are in the off state.

Each switch conducts equally well in both directions when on, making these devices suitable for both multiplexing and demultiplexing applications. Because each switch is turned on or off by a separate bit, these devices can also be configured as a type of switch array, where any, all, or none of the eight switches can be closed at any time. The input signal range extends to the supply rails. All channels exhibit break-before-make switching action, preventing momentary shorting when switching channels.

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.

EVAL-24TSSOP

Evaluation Board for 24-Lead TSSOP Devices in the Switches and Multiplexers Portfolio

Evaluation Board for 24-Lead TSSOP Devices in the Switches and Multiplexers Portfolio

Features and Benefits

  • 24-lead TSSOP evaluation board 
  • Clamp allows the main device to be easily changed 
  • Gold pin connectors allow the addition of passive components 
  • SMB connectors for the input/output of signals 
  • Additional space on-board to allow for prototyping 

Product Detail

The EVAL-24TSSOPEBZ evaluation board evaluates 24-lead TSSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-24TSSOPEBZ to secure a 24-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.


A 24-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 K24 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.
