We are developing a component test system and need to evaluate flicker noise. Having discovered T.I. Precision Labs 0.1Hz to 10Hz filter design, I am attempting to fabricate and populate the circuit board. This circuit board is not sold by T.I., however, schematics and Gerber files are made available. One drawback - the drill file is not of a format that is useful. This is preventing me from ordering PCB's. Has anyone else attempted to recreate this PCB board or know how to obtain a valid drill file? The document/app note is slau522.pdf, the schematic, BOM and gerber files are in slac592a.
Art Kay, your name is on the app note, can you help with this????
Thanks,
Mark
