CARD READ

Fig.16 Application diagram.

TDA8002C should be placed as close as possible to the card reader.

(1) Contact normally open.

(2) C3 close to pin V

of TDA8002C.

(3) C4 close to C1 contact of card reader.

(4) C5 close to VUP pin of TDA8002C.

(5) C6 as close as possible to pins S1 and S2.

CLK line may be shielded with respect to other lines.

Decoupling capacitors C7 and C8 may be placed as close as possible to pin V

DDA

A good ground plane is recommended.
