PIN FUNCTIONS
V
+
(Pins 1, 3, 10):
Positive Power Supply (Normally tied
to 3V or 3.3V). All three pins must be tied to the same
voltage. Bypass each pin with 1000pF and 0.1μF capaci-
tors as close to the pins as possible.
V
OCM
(Pin 2):
This pin sets the output common mode
voltage. A 0.1μF external bypass capacitor is recom-
mended.
V
(Pins 4, 9, 12, 17):
Negative Power Supply. All four
pins must be connected to the same voltage/ground.
–OUT, +OUT (Pins 5, 8):
Unfiltered Outputs. These pins
have 12.5
Ω
series resistors.
–OUTF, +OUTF (Pins 6, 7):
Filtered Outputs. These pins have
50
Ω
series resistors and a 1.7pF shunt capacitance.

N
A
B
L
E (Pin 11):
This pin is a logic input referenced to
V
. If low, the part is enabled. If high, the part is disabled
and draws approximately 1mA supply current.
+IN (Pins 13, 14):
Positive Input. Pins 13 and 14 are
internally shorted together.
–IN (Pins 15, 16):
Negative Input. Pins 15 and 16 are
internally shorted together.
Exposed Pad (Pin 17):
V
. The Exposed Pad must be con-
nected to the same voltage/ground as pins 4, 9, 12.
