Hi Finn ok. Now I recall you mentioning this recently but misunderstood. Sorry I haven’t read all your emails carefully enough having done the work with tracy. Good news for this EC3, that being the case. I’ll see if I have enough time tonight to reprogram the chips as I’m headed down tomorrow and could test the new code. I tried to pick up some 2.7v zeners today, but they only had 3.3v in single units and 2.7v by the 1000! So the full wave clipping circuit you supplied should clip the CAS signal to Zener voltage + forward volt drop of the other zener. 2.7+~0.7 = 3.4v. If I use the 3.3v it would clip the signal at 3.3+~0.7=4v. My analog amp knowledge is woefully lacking these days but I thought this extra 0.6v would be fine for Tracy’s conditioning circuits. Appreciate any analog insights you can offer re those signal conditioning amplifier/buffers?
