NAME
BIAS51
Amplifier Input. Use a series blocking capacitor with less than
3Ω reactance at your lowest operating frequency.
Ground Connection. For optimum performance, provide a low-
inductance connection to the ground plane.
Amplifier Output. Use a series blocking capacitor with less than
3Ω reactance at your lowest operating frequency.
Supply Connection. Bypass directly at the supply pin. The value
of the bypass capacitor is determined by the lowest operating
frequency, and is typically the same as the blocking capacitor
value. Additional bypassing may be necessary for long V
CC
lines.
Shutdown Input. Driving SHDN with a logic low turns off the
amplifier.
FUNCTION
Bias Resistor Connection. Connect a resistor to GND to set the
bias current. See the Supply Current vs. R
BIAS
graph in the
Typical Operating Characteristics.
