+5V Power Supply
HI: High Impedance State. LO or Floating: Nor-
mal Operation. Internal pull-down resistors.
Most Significant Bit Inversion, HI: MSB inverted
for complementary output. LO or Floating: Straight
output. Internal pull-down resistors.
+5V Power Supply
Bottom Reference Bypass. For external bypass-
ing of internal +1.25V reference.
Common-Mode Voltage. It is derived by
(REFT + REFB)/2.
Top Reference Bypass. For external bypassing
of internal +3.25V reference.
