LTC6404

6404f
SHDN (Pin 1): When SHDN is oating or directly tied to
V+, the LTC6404 is in the normal (active) operating mode.
When Pin 1 is pulled a minimum of 2.1V below V+, the
LTC6404 enters into a low power shutdown state. See
Applications Information for more details.
V+, V– (Pins 2, 10, 11 and Pins 3, 9, 12):
Power Supply
Pins. Three pairs of power supply pins are provided to keep
the power supply inductance as low as possible to prevent
degradation of amplier 2nd harmonic performance. See
the Layout Considerations section for more detail.

PIN FUNCTIONS
VOCM (Pin 4): Output Common Mode Reference Voltage.
The voltage on VOCM sets the output common mode
voltage level (which is dened as the average of the volt-
ages on the OUT+ and OUT– pins). The VOCM pin is the
midpoint of an internal resistive voltage divider between
the supplies, developing a (default) mid-supply voltage
potential to maximize output signal swing. In general, the
VOCM pin can be overdriven by an external voltage refer-
ence capable of driving the input impedance presented
by the VOCM pin. On the LTC6404-1, the VOCM pin has a
input resistance of approximately 23.5k to a mid-supply
