Packaging
- 1x TDA2030 Original IC
- Packed in anti-static protection sleeve
Equivalent Variants
- TDA2030A
- TDA2030AQ
(Some minor improvements in thermal behavior or output, but largely interchangeable depending on your design.)
Pro Tips for Use
- Always mount on a heatsink to prevent overheating
- Use bypass capacitors (e.g., 100nF + 470µF) across power rails
- For dual IC bridge amplifier setups, match resistor values carefully
- Keep signal ground and power ground separate to reduce hum/noise
- Always use a good heatsink for continuous operation
- Ensure filtering capacitors are present at the power rails
- Use good quality components to avoid hum or distortion
- TDA2030 can replace TDA2030A, but not vice versa
