The TDA2009 application circuit and reference materials are essential for audio amplifier designs. Below is a detailed pin configuration and voltage setup for the TDA2009 chip. This information can be helpful for engineers or hobbyists working on audio projects.
Here’s a breakdown of the pin connections:
1. Pin 1: 1.2V – Left Channel Input
2. Pin 2: 0.8V – Left Channel Feedback
3. Pin 3: 12V – Squelch (Noise Reduction)
4. Pin 4: 0.8V – Right Channel Feedback
5. Pin 5: 1.2V – Right Channel Input
6. Pin 6: 0V – Ground
7. Pin 7: 0V – Not Used / Empty
8. Pin 8: 12.4V – Right Channel Output
9. Pin 9: 24V – Power Supply
10. Pin 10: 12.4V – Left Channel Output
11. Pin 11: – – – (Not Connected)
This configuration is commonly used in stereo amplifiers, providing balanced power and signal control. If you're looking to build or troubleshoot an audio system using the TDA2009, this layout can serve as a useful reference. Always make sure to double-check voltages and connections before powering up any circuit.
Hybrid inverters charge the batteries using solar power during daylight. If the Battery goes low, or during insufficient lighting, they charge the batteries from the Grid. These systems automatically switch between the solar power and the Grid.
This is great way of replacing polluting diesel generators. Your electricity bill will be reduced and your diesel bill will be eliminated.
