Overview

  • 1 Ω typical on resistance 
  • 0.2 Ω on resistance flatness 
  • ±3.3 V to ±8 V dual-supply operation
  • 3.3 V to 16 V single-supply operation
  • No VL supply required 
  • 3 V logic-compatible inputs 
  • Rail-to-rail operation
  • See data sheet for additional features

The ADG1611 / ADG1612 / ADG1613 contain four independent single-pole/single-throw (SPST) switches. The ADG1611 and ADG1612 differ only in that the digital control logic is inverted. The ADG1611 switches are turned on with Logic 0 on the appropriate control input, while Logic 1 is required for the ADG1612 switches. The ADG1613 has two switches with digital control logic similar to that of the ADG1611; the logic is inverted on the other two switches. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.

The ADG1613 exhibits break-before-make switching action for use in multiplexer applications. Inherent in the design is the low charge injection for minimum transients when switching the digital inputs.

The ultralow on resistance of these switches make them ideal solutions for data acquisition and gain switching applications where low on resistance and distortion is critical. The on resistance profile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals.

The CMOS construction ensures ultralow power dissipation, making them ideally suited for portable and battery-powered instruments.

PRODUCT HIGHLIGHTS

  1. 1.6 Ω maximum on resistance over temperature
  2. Minimum distortion: THD + N = 0.007%
  3. 3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V
  4. No VL logic power supply required.
  5. Ultralow power dissipation: <16 nW
  6. 16-lead TSSOP and 16-lead, 4 mm × 4 mm LFCSP

EVAL-16LFCSP

Evaluation Board for the 16-Lead LFCSP Devices in the Switches and Multiplexers Portfolio

Features and Benefits

  • 16-lead, 4 mm × 4 mm LFCSP evaluation board
  • Easily changeable clamshell 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-16LFCSPEBZ enables easy evaluation of the 16-lead lead frame chip scale package (LFCSP) devices in the Switches and Multiplexers Portfolio that are purchased separately. The EVAL-16LFCSPEBZ is supplied with a clamshell socket to secure a 16-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, for board flexibility and reusability for multiple evaluations.

Figure 1 in the user guide shows the EVAL-16LFCSPEBZ. A 16-lead LFCSP device can be inserted into the socket in the center of the evaluation board. Each device pin has a corresponding three-pin header link, from K1 to K16. This can either be connected to an external signal source by removing the corresponding link or use the link to choose between VDD or GND. A wire screw terminal, J5, supplies the VDD and GND. The Subminiature Version B (SMB) connectors on the EVAL-16LFCSPEBZ allow additional external signals to be supplied to the device. In addition, there is a perfboard space and two 16-lead LFCSP pads (3 mm x 3 mm and 2.1 mm x 2.1 mm) available on top of the EVAL-16LFCSPEBZ 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-16LFCSPEBZ user guide when using the EVAL-16LFCSPEBZ.

EVAL-16TSSOP

Evaluation Board for 16 lead TSSOP Devices in the Switch/Mux Portfolio

Features and 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

Product Details

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.
