TYPICAL PERFORMANCE CHARACTERISTICS
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 capacitors
as close to the pins as possible.
VOCM (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 same voltage/ground.
–OUT, +OUT (Pins 5, 8): Unltered Outputs. These pins
have series resistors, ROUT 12.5Ω.
–OUTF, +OUTF (Pins 6, 7): Filtered Outputs. These pins
have 50Ω series resistors and a 2.7pF shunt capacitor.
ENABLE (Pin 11): This pin is a logic input referenced to
VEE. If low, the part is enabled. If high, the part is disabled
and draws very low standby current while the internal op
amp has high output impedance.
+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
connected to same voltage/ground as pins 4, 9, 12.
