TDA5345HT

RECOMMANDED OPERATING CONDITIONS

HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is

desirable to take normal precautions appropriate to handling MOS devices.

ESD according to MIL STD 883C - method 3015 (HBM 1 500

Ω, 100pF) 3 pulses (+) and 3 pulses (-) on each pin versus

ground - Class 1: 0 to 1 999 V

THERMAL RESISTANCE

This is obtained in a PCB tailored to heat dissipation : pin number 16, 32, 48, 64 have to be connected to a good ground

layer to improve the IC heat dissipation.
