PGA309: Spice model

Art Mecina

Part Number: PGA309

Hello Guys,

Good day.

Is there any available Spice model you can share to use for this device? If you can suggest any other methods of modeling it. Maybe a similar PGA or different software?

If we are to request for a model be created for this device, is that possible? Because I know there are some devices where spice models are not possible.

Thanks in advance!

Hello Art,

The PGA309 device was developed and introduced to the market more than a decade ago in 2003, and therefore no SPICE model was developed for the device. The best way to get familiar with the device is by using the PGA309EVM-USB evaluation board. The PGA309EVM-USB GUI/software includes an auto-calibration algorithm that selects the optimal gain and offset adjustment settings for a given sensor and output target requirements. The hardware also includes a sensor emulator that allows to program sensor characteristics to emulate the sensor hardware. The GUI also offers a "Block Diagram" tab that allows the user to experiment with settings. Attached find some EVM information links and power-point that can be useful. If you have further questions, please feel free to contact me directly via email.

Thank you and Regards,

Luis
