Overview

  • 1.5 pF off capacitance
  • 0.5 pC charge injection
  • 33 V supply range
  • 120 Ω on resistance
  • Fully specified at ±15 V/+12 V
  • 3 V logic-compatible inputs
  • Rail-to-rail operation
  • Break-before-make switching action
  • 16-lead TSSOP, 20-lead TSSOP, and 4 mm × 4 mm LFCSP
  • Typical power consumption (<0.03 μW)

The ADG1233 and ADG1234 are monolithic iCMOS® analog switches comprising three independently selectable single-pole, double throw SPDT switches and four independently selectable SPDT switches, respectively.

All channels exhibit break-before-make switching action preventing momentary shorting when switching channels. An EN input on the ADG1233 and ADG1234 enables or disables the device. When disabled, all channels are switched off.

The iCMOS (industrial-CMOS) modular manufacturing process combines a high voltage complementary metal-oxide semiconductor (CMOS) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no other generation of high voltage devices has been able to achieve.

Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lowered power consumption, and reduced package size.

The ultralow capacitance and charge injection of these multiplexers make them ideal solutions for data acquisition and sample-andhold applications, where low glitch and fast settling are required.

Fast switching speed coupled with high signal bandwidth make the devices suitable for video signal switching. iCMOS construction ensures ultralow power dissipation, making the devices ideally suited for portable and battery-powered instruments.

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.

  • 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.
