Hi,
On my PCB I want to have assembly option to use one of LTC2000A-16, LTC2000A-14 or LTC2000A-11. As it comes for pin compatibility, I see in DS, that pins N-S 7-10 are grounded in -11 and used as signal in -16. My question is - do those pins need to be connected to power ground (via 0R resistors) or it is sufficient that they will be driven low from FPGA (after configuration)?
