Application Information

Power Supplies

A common VCC power supply should be used for all pins requiring DC power. All supply pins should be bypassed with external capacitors to

minimize noise and fast transients. Supply noise can degrade noise figure and fast transients can trigger ESD clamps and cause them to fail.

Supply voltage change or transients should have a slew rate smaller than 1V / 20 s. In addition, all control pins should remain at 0V (+/- 0.3V)

while the supply voltage ramps up or while it returns to zero.

Control Pin Interface

If control signal integrity is a concern and clean signals cannot be guaranteed due to overshoot, undershoot, ringing, etc., the following circuit

at the input of each control pin is recommended. This applies to control pins 7 and 8 as shown below.
