The THS7373EVM is an evaluation module released by Texas Instruments. It is a fully assembled evaluation board which enables users to evaluation the TI THS7373 triple-channel SPDT analog switch. The board is designed to show the performance of the THS7373 in a wide variety of applications, such as in audio routing, digital audio system, and video switching.

Application Field

This module is designed to provide a platform for testing the performance and functions of the TI THS7373 triple-channel, single-pole-double-throw (SPDT) analog switch. It can be used in a variety of applications, such as audio routing, digital audio system, and video switching. It can be used for prototyping, system integration and verification of audio routing, digital audio systems, video switching, video ADC/DAC switching, etc.

Features

• Integrated THS7373 triple-channel, single-pole-double-throw (SPDT) analog switch.
• Fully programmable switch settings.
• Fully featured, on-board electronic control.
• Integrated power supply and external power options (optional).
• Small form factor board.

Working Principle

The THS7373EVM has two main parts: the THS7373, and the EVM. The THS7373 is a SPDT analog switch which is capable of switching three analog signals between two ports. Each switch channel has two switches, a “closed” squelch switch and an “open” squelch switch. The state of the switch (open or closed) is determined by the control signals sent to the switces by the EVM.

The EVM provides the control signals to the THS7373. It also provides the power supply required to drive the switch. The EVM has an on-board electronic controller which can provide up to five control signals to the switch. The control signals can be either programmed or controlled by the PC board (included). All of the features can be programmed through the on-board I/O connectors.

Conclusion

The THS7373EVM is a fully assembled evaluation board which enables users to evaluation the TI THS7373 triple-channel SPDT analog switch. It provides a platform for testing the performance and functions of the TI THS7373 and can be used in a variety of applications, such as audio routing, digital audio system, and video switching. It is a great tool for prototyping, system integration, and verification of audio routing, digital audio systems, video switching, video ADC/ DAC switching, etc.
