The α24 fully-differential line amplifier

Circuit board

The α24 circuit board is made of high quality FR-4 glass epoxy, double-layer with plated-through holes as well as silkscreen and soldermask. Ground planes on both sides of the board provide low ground impedance and RFI shielding.

The following diagram illustrates some important board dimensions. It can be used as a reference when you work on the chassis enclosure.

Below are photo images of the top and bottom of circuit board. They are not in actual size.


The circuit board layout is shown below. The top layer is shown in red, the bottom layer is in blue, areas where there are traces in both the top and bottom layers are in lavender, and the top silkscreen is in light grey.
