ESD protection and compliance
To provide excellent ESD immunity, an audio line IPAD(a) (STMicroelectronics reference
EMIF04-EAR02M8) can be added at the output of the TS4604 (Figure 54).
By adding the IPAD, the TS4604 complies with the standard IEC 61000-4-2 level 4 on the
external pins.
●
OUT_HPL and OUT_HPR for the headphone driver.
●
OUT_LDL and OUT_LDR for the Line driver.
