Point of Application Board Design
1. Notes on Application board’s pattern design
For increasing stability, the connected line of V
lower impedance.
For increasing stability, it is better to place the capacitor between V
IC.
For increasing stability, it is better to place C1 to C8 and R1 to R8, which are for stopping
oscillation, close to IC.
It is better to place the grounding of resistor (Rg), between input line and ground, close to INGND
(Pin 12) because if OUTGND is connected to the line between Rg and INGND, THD will become
worse due to current from OUTGND.
