Overview

  • SPI/QSPI/MICROWIRE-compatible interface
  • 2.7 V to 5.5 V single supply
  • ±2.5 V dual supply
  • 2.5 Ω on resistance
  • 0.6 Ω on resistance fatness
  • 0.1 nA leakage currents
  • Octal SPST
  • Power-on reset
  • Fast switching times
  • TTL/CMOS compatible
  • 24-lead TSSOP and 24-lead LFCSP

The ADG714 is a complementary metal-oxide semiconductor (CMOS), octal single-pole, single-throw (SPST) switch controlled via a 3-wire serial interface. On resistance is closely matched between the switches and is flat over the full signal range. Each switch conducts equally well in both directions, and the input signal range extends to the supplies. Data is written to these devices in the form of 8 bits, each bit corresponding to one channel.

The ADG714 uses a 3-wire serial interface that is compatible with serial peripheral interface (SPI), QSPI™, MICROWIRE™ interface standards, and most digital signal processing (DSP) interface standards. The output of the shift register DOUT enables a number of these devices to be daisy-chained.

On power-up, all switches are in the OFF condition, and the internal registers contain all zeros.

A low power consumption and operating supply range of 2.7 V to 5.5 V makes this part ideal for many applications. The ADG714 may also be supplied from a dual ±2.5 V supply. The ADG714 is available in a 24-lead TSSOP and a 24-lead LFCSP.

Product Highlights

  1. 3-wire serial interface.
  2. Single-/dual-supply operation.
    The ADG714 and ADG715 are fully specified and guaranteed with 3 V, 5 V, and ±2.5 V supply rails.
  3. Low on resistance, typically 2.5 Ω.
  4. Low leakage.
  5. Power-on reset.
  6. A 24-lead TSSOP.
  7. A 24-lead LFCSP.

Applications

  • Data acquisition systems
  • Communication systems
  • Relay replacement
  • Audio and video switching

EVAL-24TSSOP

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

Buy Now View Details

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 Details

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.

EVAL-24LFCSPEBZ

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

Buy Now View Details

Features and Benefits

  • 24-lead, 4 mm × 4 mm LFCSP evaluation board
  • Easily changeable socket for the main device
  • Gold pin connectors for the addition of passive components
  • SMB connectors for the input and output of signals
  • Additional space on board for prototyping

Product Details

The EVAL-24LFCSPEBZ enables easy evaluation of the 24-lead lead frame chip scale package (LFCSP) devices in the Switches and Multiplexers Portfolio portfolio that are purchased separately. The EVAL-24LFCSPEBZ is supplied with a socket to secure a 24-lead LFCSP device to the evaluation board without the need for soldering. In addition, there are three sets of gold pin connectors in each trace, allowing board flexibility and reusability for multiple evaluations.

Figure 1 shows the EVAL-24LFCSPEBZ. A 24-lead LFCSP device can be inserted into the socket in the center of the evaluation board. Each device pin has a corresponding 3-pin header link, from K1 to K24, that can either be connected to an external signal source by removing the corresponding link or by using the link to choose between VDD or GND. A wire screw terminal, J1, supplies the VDD and GND. The Subminiature Version B (SMB) connectors on the EVAL-24LFCSPEBZ allow additional external signals to be supplied to the device. In addition, there is a perfboard space and two 24-lead LFCSP pads (4 mm × 4 mm) available on top of the EVAL-24LFCSPEBZ for prototyping.

The full specifications of the device under test (DUT) are available in the corresponding product data sheet, which must be consulted with the EVAL-24LFCSPEBZ user guide when using the EVAL-24LFCSPEBZ.
