LTC6404-2
TYPICAL PERFORMANCE CHARACTERISTICS
PIN FUNCTIONS
SHDN (Pin 1): When SHDN is fl oating or directly tied to V
the LTC6404-2 is in the normal (active) operating mode.
When Pin 1 is pulled a minimum of 2.1V below V
LTC6404-2 enters into a low power shutdown state. See
Applications Information for more details.
V
Pins. Three pairs of power supply pins are provided to keep
the power supply inductance as low as possible to prevent
degradation of amplifi er 2nd harmonic performance. See
the Layout Considerations section for more detail.
