Overview

  • Latch-up proof
  • 3 pF off source capacitance
  • 5 pF off drain capacitance
  • 0.07 pC charge injection
  • Low leakage: 0.2 nA maximum at 85ºC
  • ±9 V to ±22 V dual-supply operation
  • 9 V to 40 V single-supply operation
  • 48 V supply maximum ratings
  • Fully specified at ±15 V, ±20 V, +12 V, and +36 V
  • VSS to VDD analog signal range

The ADG5212 / ADG5213 contain four independent single-pole/single-throw (SPST) switches. The ADG5212 switches turn on with Logic 1. The ADG5213 has two switches with digital control logic similar to that of the ADG5212; however, the logic is inverted on the other two switches. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked.

The ADG5212 and ADG5213 do not have a VL pin. The digital inputs are compatible with 3 V logic inputs over the full operating supply range.

The ultralow capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. Fast switching speed together with high signal bandwidth make the parts suitable for video signal switching.

APPLICATIONS

  • Automatic test equipment
  • Data acquisition
  • Instrumentation
  • Avionics
  • Audio and video switching
  • Communication systems

PRODUCT HIGHLIGHTS

  1. Trench Isolation Guards Against Latch-Up. A dielectric trench separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions.
  2. Ultralow capacitance and < 1 pC charge injection.
  3. Dual-Supply Operation. For applications where the analog signal is bipolar, the ADG5212 / ADG5213 can be operated from dual supplies up to ±22 V.
  4. Single-Supply Operation. For applications where the analog signal is unipolar, the ADG5212 / ADG5213 can be operated from a single rail power supply up to 40 V.
  5. 3 V Logic Compatible Digital Inputs. VINH = 2.0 V, VINL = 0.8 V.
  6. No VL Logic Power Supply Required.

EVAL-16LFCSP

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

Buy Now View Details

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.

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.
