Figure 17 : Bridge Amplifier Configuration with Split Power Supply (PO = 24W, VS = ± 12V)
lete Product(s) PRACTICAL CONSIDERATIONS
o Printed Circuit Board
s The layout shown in Figure 14 should be adopted
b by the designers. If different layout are used, the
O ground points of input 1 and input 2 must be well
- decoupled from ground of the output on which a
t(s) rather high current flows.
Assembly Suggestion
c No electrical isolation is needed between the pack-
age and the heat-sink with single supply voltage
configuration.
Application Suggestion
The recommended values of the components are
the ones shown on application circuits of Figure 13.
Different values can be used. The table 1 can help
the designers.
