SKU: Q8IV Category:


This driver module, designed for silicon photonics, contains 8 ultra-precise fully programmable channels. It uses a new card-edge connector system which is easier to use and more robust than its predecessor. Adapters are available. Next-generation fully shielded backplane, cable, and interposer infrastructure to fit the new connectors are now available. Drop us an email at [email protected] with requests and enquiries.


  • 8 software-defined input/output channels
    • Channels configurable as voltage output, current output, ground, voltage or current sense
  • Hardware voltage and current control (12 V, 24 mA)
  • 16-bit output precision (±180 µV, ±370 nA)
  • 18-bit input accuracy

Output circuit diagram

Referring to the diagram, nominal performance values are as follows. Values with ‘±’ are digitisation step sizes (i.e. resolution) and also target accuracy.

  • a = 0..12 V ± 180 µV @ +15 mA max
  • b = 0..24 mA ± 370 nA @ 15 V max
  • c = 1.6 Ω max
  • d = –24..+24 mA ± 740 nA
  • e = 0..12 V ± 50 µV

    1. Hi Lyndon, thanks for your interest! If you optimise your control on the software side (using our binary command set, flushing serial buffers properly, etc.) this hardware can reach a little beyond 1000 updates per second. Feel free to drop us an email for more info/data!

    1. Hi Hossam! Thank you for pointing out this ambiguity. We’ve now updated the website to clarify that these are the maximum and minimum input voltages from the power supply.
