Description

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 atย [email protected]ย with requests and enquiries.

Features

  • 8ย 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 (ยฑ180 ยตV, ยฑ370 nA)
  • 18-bit input accuracy

Output circuit diagram
