EVALUATION KIT
FOR SA03 PIN-OUT
A block diagram of the amplifier is shown in Figure 2
along with pcb connections of all the commonly used
external components. Your application circuit will not
use all of the components. Add those components
required by your circuit. You may have to jumper
some components to make the desired electrical
connections. J1 is an optional way to connect the
clock circuit. Power supply bypassing is particularly
important and that is why high quality ceramic chip
capacitors are supplied with the kit. In addition you
may need to add a 10-50 uF or larger capacitor on
the +Vs pin. This additional capacitor needs to be
rated for switching operation. Note that the signal
ground and power ground are separated and tie
together only at the ground pin (5). A breadboarding
area is supplied which can accomodate 1 or 2 IC
amplifiers and associated components. The large
terminal pads can be used to solder wire connec-
tions or banana jacks.
