FIGURE 3. PCB SCHEMATIC.

A block diagram of the SA08 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 op-

tional 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, a large

electrolytic capacitor is included. This capacitor

was selected expressly for this evaluation kit

and may not be (and likely won't be) suitable

for your end application. You will need to select

an electrolytic capacitor based on your analysis

of the capacitor's ripple current, ripple current

tolerance, operating temperature, operating

voltage, acceptable service life and acceptable

supply ripple. 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

connections or bannana jacks.
