Description
External resistor from RSINK to VNN sets output current sinking limit. Current limit is
approximately 12.5V divided by RSINK resistor value.
External resistor from RSOURCE to VNN sets output current sourcing limit. Current limit is
approximately 12.5V divided by RSOURCE resistor value.
Internally generated reference voltage. An external low voltage (1.0 - 10nF) capacitor needs to
be connected across VPP and BYP-VPP.
High voltage positive supply. There are two pads.
