(1) Place close to the protected pin with good (low resistive) and straight connection to the main ground.
(2) Place close to the supply pin with good (low resistive) and straight connection to GNDP.
(3) Place close to TDA8035´s VCC pin with good connection to GNDC.
(4) Place close to card connector´s C1 (VCC) pinwidth good connection to GNDC.
(5) Optional bridge. If not used, R1 must be O Ohm and R2 absent (direct connection to VDDI).
(6) GNDP and GNDC must be connected to the main ground with a straight and low resistive connection
