    Hi attila, All my work is on IC's and voltages supplies below 5.5v. Worst case I can think of is a ground path via the analog channel for 7-8mA tops. Would all 4 op amps fail simultaneously? Why are 3 channels negative and 1 positive? If you provide schematics I can test individual IC's to help diagnose. Thanks, Kurt

    Good day. I have purchased 2 ADP3450s 13 and 12 months ago. The first one is now faulty where the scope / analog channels are now clamped. The waveform generator and digital are OK. Firstly what can be done to repair this device as it is a staple for my work? Secondly is this an ongoing issue with the product line? Do I need to repair / return the 2nd? I wanted to purchase an additional one for my team and has any update to design or QC been made since last purchase (May 2021)?
