Q8b driver module

Q8b driver module

8-channel precise and economical voltage-output driver module.

Description

This economical driver module contains 8 precise voltage-programmable channels. It uses our new card-edge connector system which is easier to use and more robust than its predecessor. It works with our next-generation fully-shielded backplane, cable, and interposer infrastructure.

Features

• 8 software-defined output channels
• Channels configurable as voltage output, ground, or current sense
• Source and sink current
• Hardware voltage control (12 V, 50 mA)
• 16-bit output precision (±180 µV)
• 12-bit input precision

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 @ +50 mA/-500 mA source/sink max
• c = 1.6 Ω max
• d = –100..+100 mA ± 49 µA
