Opto-emulators offers significant reliability and performance advantages compared to optocouplers, including wider temperature ranges and tight process controls resulting in small part-to-part variation. Since there is no aging effect or temperature variation to compensate for, the emulated diode-input stage consumes less power compared to optocouplers, which have LED aging and require higher bias currents over the device lifetime.

• Platform for complete evaluation of opto-emulators with different package footprint options
• Break-away design allows for easy separation of board footprints
• Test points and jumper options
• Passives and footprints for basic modifications included
• One channel diode-emulator input
• Robust isolation barrier

The ISOM-EVM supports evaluation of TI's Opto-emulators in a 5-pin DFF, 4-pin DFG, 4-pin DFH, and 4-pin DFS SOIC packages. The EVM can be reconfigured for evaluation for different Opto-emulators, different input signal, or other applications by changing the EVM configuration and component values. The EVM does not have Opto-emulator ICs mounted on the board to allow the user to mount a compatible IC of their own choosing. The user can break apart the board into three separate units to test the PCBs individually. The user's guide also covers the pin configuration of Opto-emulators, EVM schematic, and typical setup.

This evaluation module contains one PCB evaluation board. The major components of the ISOM-EVM evaluation board are:

• Multiple Opto-emulator footprint compatibility
• Multiple on-board test points
• Input and output headers

To demonstrate functionality of the Opto-emulators, TI recommends the following (not included):

• Oscilloscope
• Signal generator
