l  18位输入精度


 

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. Initial quantities are limited.

Features

n  8 software-defined input/output channels

n  Channels configurable as voltage output, current output, ground, voltage or current sense

n  Hardware voltage and current control (12 V, 24 mA)

n  16-bit output precision (±180 µV, ±370 nA)

n  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.

n  a = 0..12 V ± 180 µV @ +15 mA max

n  b = 0..24 mA ± 370 nA @ 15 V max

n  c = 1.6 Ω max

n  d = –24..+24 mA ± 740 nA

n  e = 0..12 V ± 50 µV
