Hi all, The company I work for is having a problem with a unit we make. Looking over the schematic, it is using a TSC500ACPE & TSC520CPD as an ADC. This is an old Teledyne chipset. However, I can't find a datasheet on them. Any pointers? Also, anyone have an idea of what this chipset costs? Thanks! Bill --=20 Psst...=A0 Hey, you...
