TDA2005M

Overview

The TDA2005M is a Class B dual audio power amplifier in Multiwatt11 package designed for car radio applications. It provides high current capability up to 3.5 A and drives low impedance loads down to 1.6 Ω. In bridge configuration, it delivers over 20 W output power at 4 Ω with 1% distortion. The device features comprehensive protection against short circuits, thermal overload, load dump surges, open ground, and inductive loads.

Feature Summary

• High output power capability with high current drive
• Integrated protection systems including thermal shutdown and short circuit protection
• Flexible application modes supporting bridge or stereo configurations
• Low external component count for simplified design

Applications

• Car radio power booster amplifiers
• Bridge amplifier configurations
• Stereo amplifier applications
• Bus amplifiers
• Two-way speaker amplifiers

Procurement Notes

Verify the ordering suffix 'M' confirms the bridge application variant. Confirm the Multiwatt11 package type matches the heatsinking requirements. Ensure supply voltage limits are respected within the absolute maximum ratings. Check for specific protection circuit needs regarding load dump voltage surges.

Selection Notes

Select this component for automotive audio systems requiring high power density. Consider the thermal resistance of the heatsink for power dissipation calculations. Evaluate the need for bootstrap capacitors based on the chosen gain and bandwidth settings. Verify compatibility with low impedance loudspeaker loads.

Part Context

The TDA2005 series includes variants like TDA2005S for stereo applications. It belongs to STMicroelectronics' line of class B audio power amplifiers. The Multiwatt11 package allows direct mounting to heatsinks without electrical isolation.

Replacement Considerations

TDA2005S is documented as the stereo application variant.
