Notes and Changes:

Version 6 documents the change from LT1492 to AD8622 for the input and output buffers. This change addresses excess low frequency (10Hz) noise (Popcorn Noise) found in the LT1492.

The manufacturing files (Gerber etc.) remain the same from version 5.

This dcc entry is confusing, since it describes both the AI/AA filter board as well as the ISC AI chassis. When used as an ISC AI chassis the front panel is D1100130 and the rear panel is D1100131. When retrofitted for the LIGO DAC, the rear interface changes to a D2500097 using rear panel D2400308.
