DESCRIPTION

The TDA 2003 hasimproved performancewith the

same pin configuration as the TDA 2002.

The additional features of TDA 2002, very low

numberof externalcomponents,ease of assembly,

space and cost saving, are maintained.

Thedeviceprovidesa high outputcurrentcapability

(up to 3.5A) very low harmonic and cross-over

distortion.

Completely safe operation is guaranteed due to

protectionagainst DCand ACshort circuit between

all pins and ground,thermal over-range,load dump

voltage surge up to 40V and fortuitous open

ground.

Load dump voltage surge

The TDA 2003 has a circuit which enables it to

withstanda voltagepulse train, on pin 5, of the type

shown in fig. 19.

If the supply voltage peaks to more than 40V, then

an LC filter must be inserted between the supply

and pin 5, in order to assure that the pulses at pin

5 will be held within the limits shown in fig. 18.A
