+OUTFILTERED, –OUTFILTERED (Pins 6, 7): Filtered
Outputs. These pins add a series 25
Ω resistor from the
unltered outputs and three 12pF capacitors. Each output
has 12pF to VEE, plus an additional 12pF between each pin
(See the Block Diagram). This lter has a –3dB bandwidth
of 175MHz.
ENABLE (Pin 11): This pin is a TTL logic input referenced
to the VEEC pin. If low, the LT1993-4 is enabled and draws
typically 100mA of supply current. If high, the LT1993-4
is disabled and draws typically 250A.
–INA, –INB (Pins 14, 13): Negative Inputs. These pins are
normally tied together. These inputs may be DC- or AC-
coupled. If the inputs are AC-coupled, they will self-bias
to the voltage applied to the VOCM pin.
+INA, +INB (Pins 16, 15): Positive Inputs. These pins are
normally tied together. These inputs may be DC- or AC-
coupled. If the inputs are AC-coupled, they will self-bias
to the voltage applied to the VOCM pin.
Exposed Pad (Pin 17): Tie the pad to VEEC (Pin 12). If split
supplies are used, DO NOT tie the pad to ground.
