TDA7330B
APPLICATION SUGGESTION
A good DC decoupling between VCC and
GROUND is necessary: a 100nF ceramic ca-
pacitor, with low resistance and low inductance
at high frequency, directly connected on pin 16
(VCC)and 5 (GND) is recommended.
A small series inductance (100µH) or resistor
(27Ω) may be used for supply line filtering.
The Layout path pin2 - C2 - pin5 must be as
short as possible.
If the supply line, after the power on has a soft
and disturbed (spikes) slope, a capacitor of
100nF, between POR and VCC, is racom-
mended.
The various testing pins have no sense for the
customer.
