Reference voltage noise (08/22/07)
On all previous assemblies ( B, C ) the TLV431 does not over-drive the ADV7343 internal reference correctly. This causes noise on the display. The solution is to use the AD7343 internal reference. This can be done by removing R171, R175, and U16 on all previous assemblies. This change has no software affect on the boards.
