Are the unused pins (1-4, 6-9) on the LM4050QML-SP connected to anything internally?
Looking at an application where two LM4050 references will be stacked to double the reference voltage. Basically, pin 5 of the upper Ref will be connected to pin 10 of the lower Ref. Pin 5 of the lower LM4050 will be connected to ground. Can pins 1-4 and 6-9 of the upper LM4050 be connected to system ground?
