Product Description
The headphone amplifier adopts NE5534 dual op amp integrated circuit with RC original. TPA6120A is a stereo ADC with a sampling frequency of 216KHZ with dynamic range 124DB signal-to-noise ratio introduced by TI. When (THD+N) is 0.00014%, it uses a±12V voltage to provide 80mW to 600O. Power; current feedback architecture; dynamic range greater than 120dB; SNR is 120dB; output noise at a gain of 2V/V is 5µV; operating voltage range: ±5~±15V; conversion rate: 1300V/µs; differential input; Get low crosstalk; short circuit and thermal protection
product details
1. Use original Toshiba TPA6120A and NE5534.
2. The electrolytic capacitor signal main circuit adopts Siemens, and the main filter capacitor adopts the capacity of Nikon 2×3300UF, which guarantees a strong and continuous power support.
3. The resistance uses five-ring metal resistors, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
4. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. PCB quality.
5. The wiring layout of the whole circuit board is quite rigorous and reasonable, and the whole PCB wiring adopts one-point grounding method. In the middle of the night when people are quiet, the earphones can hardly hear the noise, and it is very quiet.
6. Use UPC1237 and Hongfa relay for output delay protection
7. The two red switches are the gain switches of the corresponding channels
