–OUTF, +OUTF (Pins 6, 7): Filtered Outputs. These pins
have 50Ω series resistors and a 2.7pF shunt capacitor.
⎯ E ⎯ N ⎯ A ⎯ B ⎯ L ⎯ E (Pin 11): This pin is a logic input referenced to
V
and draws approximately 1mA supply current.
+IN (Pins 13, 14): Positive Input. Pins 13 and 14 are
internally shorted together.
