Notes:

1. The amplifier should be connected directly to a +9 V regulator; no dropping resistor is required.

2. If no DC signal is present at the input (pin 1), C1 can be removed. The gate (input pin) is internally grounded in the amplifier.

3. R1 is used as a placeholder for a different application circuit. It can be removed from the circuit.

4. Component sizes are 0603 unless otherwise noted.
