PIN FUNCTIONS V+ (Pins 1, 3, 10):
Positive Power Supply (Normally tied
–OUTF, +OUTF (Pins 6, 7):
Filtered Outputs. These pins to 3V or 3.3V). All three pins must be tied to the same have 50Ω series resistors and a 2.7pF shunt capacitor. voltage. Bypass each pin with 1000pF and 0.1μF capacitors
ENABLE (Pin 11):
This pin is a logic input referenced to as close to the pins as possible. VEE. If low, the part is enabled. If high, the part is disabled
VOCM (Pin 2):
This pin sets the output common mode and draws very low standby current while the internal op voltage. A 0.1μF external bypass capacitor is recom- amp has high output impedance. mended.
+IN (Pins 13, 14):
Positive Input. Pins 13 and 14 are
V– (Pins 4, 9, 12, 17):
Negative Power Supply. All four internally shorted together. pins must be connected to same voltage/ground.
–IN (Pins 15, 16):
Negative Input. Pins 15 and 16 are
–OUT, +OUT (Pins 5, 8):
Unfi ltered Outputs. These pins internally shorted together. have series resistors, ROUT 12.5Ω.
Exposed Pad (Pin 17):
V–. The Exposed Pad must be connected to same voltage/ground as pins 4, 9, 12. 64008f 8
