Audio Amplifiers Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the Pentawatt package variant. Confirm datasheet revision matches design requirements. Ensure application circuit layout follows recommended grounding practices to prevent oscillation. Validate component values for gain setting and frequency stability before production.

Audio Amplifiers Selection Notes

Select this device for applications requiring robust automotive-grade audio amplification with high current capability. The integrated protections simplify system design by eliminating external safety circuits. Consider the thermal resistance and case temperature limits when designing heatsinking solutions for continuous operation.

Audio Amplifiers Part Context

The TDA2003H belongs to the TDA200x series of audio amplifiers. It shares pin configuration with the TDA2002 but offers improved performance characteristics. The H suffix denotes the Pentawatt through-hole package suitable for higher power dissipation applications compared to surface mount variants.

Audio Amplifiers FAQ

Can the TDA2003 drive inductive loads?

Yes, an internal protection diode between pins 4 and 5 allows the device to safely drive inductive loads, such as coupling transformers for audio modulation.

What happens if the supply voltage exceeds 18V?

The maximum operating supply voltage is 18V. However, the device can withstand DC voltages up to 28V without damage. For pulses exceeding 40V, an LC filter is required on pin 5.
