TDA2003
10W CAR RADIO AUDIO AMPLIFIER
DESCRIPTION
The TDA 2003has improved performance with the same pin configuration as the TDA 2002.
The additional features of TDA 2002,very low numberof externalcomponents,ea of asmbly,space and cost saving,are maintained.
情人分手Thedevice provides a high outputcurrentcapability (up to 3.5A)very low harmonic and cross-over distortion.
Completely safe operation is guaranteed due to protectionagainst DC and ACshort circuit between all pins and ground,thermal over-range,load dump voltage surge up to 40V and fortuitous open ground.

经期能不能吃芒果The TDA2003has a circuit which enables it to withstand a voltage pul train,on pin5,of the type shown in fig.19.
If the supply voltage peaks to more than40V,then an LC filter must be inrted between the supply and pin5,in order to assure that the puls at pin 5will be held within the limits shown in fig.18.A suggested LC network is shown in fig.19.With this network,a train of puls with amplitude up to 120V and width of2ms can be applied at point A. This type of protection is ON when the supply voltage(puld or DC)exceeds18V.For thisreason the maximum operating supply voltage is18V.
