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 operat-
ing frequency.
Supply Connection. Bypass directly at the package pin. The value of the bypass capacitor is deter-
mined by the lowest operating frequency and is typically the same as the blocking capacitor value.
