EVAL-ADuMQSEBZ评估板

The EVAL-ADuMQSEBZ can be used with most Coupler® isolation products in the 16-lead, wide-body SOIC and QSOP packages. The evaluation board supports the common pad positions for power, ground, and I/O pins found in nearly all of the Coupler products and is a configurable board that can be adapted to many Coupler products.

EVAL-ADuMQSEBZ评估板主要特性:

Convenient connections for power through screw terminal blocks

Add-on BNC connector for 50 Ω signal sources

On-board signal routing

Support for signal wrap back

Simple signal paths to reduce transmission line effects

Pull-up and pull-down provided for control lines

Support for isoPower

Project area that supports surface-mount and through-hole devices
