PRACTICAL CONSIDERATIONS
Printed Circuit Board
The layout shown in Figure 14 should be adopted
by the designers. If different layout are used, the
ground points of input 1 and input 2 must be well
decoupled from ground of the output on which a
rather high current flows.
Assembly Suggestion
No electrical isolation is needed between the pack-
(*) Closed loop gain must be higher than 24dB.
