OP AMP
Solder an op amp to either the IC
a circuit requiring two op amps, solder an additional op amp
to either IC
each side of the PCB.
BYPASSING
Install the following capacitors:
C
C
SHUTDOWN
To use the shutdown feature of the amplifier in either the
SOT-23 or the SC-70 package, install a resistor at R
optional capacitor at C
S/D-A or S/D-B depending on the package of the amplifier
being used.
INPUT AND OUTPUT
SMA connectors are used for the input and output of signals.
They are located on the edges of the PCB.
