Circuit Board Material: .014” FR-4, 4 layers, .062” total thickness
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, C1 can be removed. The input is internally grounded in the amplifier.
3.
C2, C3, C5, & R1 are not used in the circuit. R2 is shorted across with 0 in the circuit. These placeholders shown in
the silkscreen are for applications with other devices.
