Features and Benefits
- 4.7 Ω maximum on resistance at 25°C
- 0.5 Ω on-resistance flatness
- Fully specified at ±15 V/+12 V/±5 V
- 3 V logic-compatible inputs
- Up to 115 mA continuous current per channel
- Rail-to-rail operation
- Break-before-make switching action
- 16-/20-lead TSSOP and 4 mm × 4 mm LFCSP
The ADG1433 and ADG1434 are monolithic industrial CMOS (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 that prevents momentary shorting when switching channels. An EN input on the ADG1433 (LFCSP and TSSOP) and ADG1434 (LFCSP only) is used to enable or disable the device. When disabled, all channels are switched off.
The iCMOS modular manufacturing process combines 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 a conventional CMOS process, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.
The ultralow on resistance and on resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. iCMOS construction ensures ultralow power dissipation, making the devices ideally suited for portable and battery-powered instruments.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
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.
Features & 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
