TIPD189
概覽
This reference design details a high-fidelity headphone amplifier circuit suitable for portable applications, such as smartphones and tablets. It uses an operational amplifier (op amp) with low power consumption and a very small package to convert a differential output voltage to a single-ended signal suitable for headphones. The design achieves -110.2dB THD+N at >50mW of output power into 32Ω headphones.
特點
- Low power consumption (1.6mA/Ch) to maximize battery life
- Extremely small solution size for space-constrained designs
- >50mW output power (32Ω), suitable for a range of headphones
- -106.7dB THD+N (1kHz, 10mW, 32Ω) for exceptional audio quality
- 31mΩ output impedance
- Stable into most headphones without series resistance
已開發完全組裝的電路板，僅供測試與性能驗證，且為非賣品。
