Test conditions unless otherwise noted:

VDD=+5 V, Temp=+25°C.

TQL9062-PCB (Reduced Current)

Notes

1.

Placing a 43K Ohm shunt resistor at the input of the amplifier reduces the current draw from 120mA to 70mA.

2.

Negligible change in s-parameter performance under reduced current conditions. OIP3 performance shown in above plot.
