Notes:

1. The amplifier should be connected directly to a +5 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 is internally grounded in the amplifier.

3. R2 is used as a placeholder for a different application circuit. It can be removed from the circuit.

4. C2 (from the silkscreen) is not utilized in this application circuit.
