LTC1968的4脚究竟是NC还是负电压?
Hello:
On the LTC1966, Pin 4 was a negative supply pin, allowing for connection of +/-5V supplies.
But for the LTC1967 and 1968, those are single 5V supply parts. Pin 4 is not connected to anything; it has no bond wire.
You can do anything you want with Pin 4 on LTC1968. It is just a floating piece of metal.
Best regards, Glen.
但ADI官方的开发板上,这个脚是接负电压的,无论是LTC1966还是LTC1968
