pin FuncTions
+IN,–IN(Pins2,6):Non-InvertingandInvertingInputPins.
SHDN (Pin 3): When SHDN is floating or directly tied to
V+, the LTC6409 is in the normal (active) operating mode.
When the SHDN pin is connected to V, the part is disabled
and draws approximately 100A of supply current.
V+, V(Pins 4, 9 and Pins 8, 10): Positive and Negative
Power Supply Pins. Similar pins should be connected to
the same voltage.
VOCM (Pin 5): Output Common Mode Reference Voltage.
The voltage on this pin sets the output common mode
voltage level. If left floating, an internal resistor divider
develops a default voltage of 1.25V with a 5V supply.
+OUT, –OUT (Pins 7, 1): Differential Output Pins.
Exposed Pad (Pin 11): Tie the bottom pad to V. If split
supplies are used, DO NOT tie the pad to ground.
