AZC002-02N

Low Capacitance ESD Protection Array

For High Speed Data Interfaces

2. Audio Interface ESD Protection

For the audio interface, the Right/Left

channels should be protected from the ESD

stress. The AZC002-02N can be used for the

audio interface ESD protection. The ESD

protection scheme for audio interface is shown in

the Fig. 4. In the Fig. 4, the Right and Left

channels of audio connector are connected to

ESD protection pins (such as pin 2 and pin 3) of

AZC002-02N. For the power pin (pin 4) of

AZC002-02N, it should directly connect to the

VDD power supply. As well, for the ground pin

(pin 1) of AZC002-02N, it should directly connect

to the Ground plate.

When ESD voltage pulse appears on the

Right/Left channel of audio connector, the ESD

pulse current will be discharged by AZC002-02N.

Therefore, the Right/Left channels of audio chip

are complementally protected with an

AZC002-02N.
