TEA2025B Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the TEA2025B?
  The recommended operating voltage range for the TEA2025B is 9V to 18V, with a typical voltage of 12V.
• How do I ensure the TEA2025B is properly biased for optimal performance?
  To ensure proper biasing, connect the VCC pin to a stable voltage source, and decouple it with a 10uF capacitor to ground. Also, ensure the input signal is within the recommended range of 100mV to 1V.
• What is the maximum power handling capacity of the TEA2025B?
  The TEA2025B can handle a maximum power of 20W, but it's recommended to operate it within 10W to 15W for optimal performance and reliability.
• How do I reduce noise and hum in my audio circuit using the TEA2025B?
  To reduce noise and hum, use a well-regulated power supply, decouple the VCC pin with a 10uF capacitor, and use a noise filter capacitor (e.g., 100nF) between the input and ground. Also, ensure good grounding and shielding of the circuit.
• Can I use the TEA2025B as a headphone amplifier?
  Yes, the TEA2025B can be used as a headphone amplifier, but it's essential to ensure the output power is limited to avoid damaging the headphones. A maximum output power of 100mW per channel is recommended.
