The ADG736 is a monolithic device comprising two independently selectable CMOS single pole, double throw (SPDT) switches. These switches are designed using a submicron process that provides low power dissipation yet gives high switching speed, low on resistance, low leakage currents, and wide input signal bandwidth.

The on resistance profile is very flat over the full analog signal range. This ensures excellent linearity and low distortion when switching audio signals. Fast switching speed also makes the part suitable for video signal switching.

The ADG736 operates from a single 1.8 V to 5.5 V supply, making it ideally suited to portable and battery-powered instruments.

Each switch conducts equally well in both directions when on, and each has an input signal range that extends to the power supplies. The ADG736 exhibits break-before-make switching action.

The ADG736 is available in a 10-lead MSOP package.

PRODUCT HIGHLIGHTS

  1. 1.8 V to 5.5 V Single-Supply Operation. The ADG736 offers high performance, including low on resistance and fast switching times. It is fully specified and guaranteed with 3 V and 5 V supply rails.
  2. Very Low RON (4.5 Ω Maximum at 5 V, 8 Ω Maximum at 3 V). At a supply voltage of 1.8 V, RON is typically 35 Ω over the temperature range.
  3. Low On Resistance Flatness.
  4. −3 dB Bandwidth > 200 MHz.
  5. Low Power Dissipation. CMOS construction ensures low power dissipation.
  6. Fast tON/tOFF.
  7. Break-Before-Make Switching Action.
  8. 10-Lead MSOP Package.

APPLICATIONS

  • USB 1.1 signal switching circuits
  • Cell phones
  • PDAs
  • Battery-powered systems
  • Communications systems
  • Sample-and-hold systems
  • Audio signal routing
  • Audio and video switching
  • Mechanical reed relay replacement

Evaluation Kits

eval board
EVAL-10MSOP

Evaluation Board for 10-Lead MSOP Devices in the Switches and Multiplexers Portfolio

Features and Benefits

  • 10-lead MSOP 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 Details

The EVAL-10MSOPEBZ evaluation board evaluates 10-lead MSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-10MSOPEBZ to secure a 10-lead MSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.


A 10-lead MSOP 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 K10 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.
