Amplifier Input. Use a series blocking capacitor with less than

3

Ω 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

3

Ω 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

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

Typical Operating Characteristics.
