1pc TPA6120A Headphone Amplifier Board ALPS Tuning Deluxe Edition AC 15V

Description: TPA6120A Headphone Amplifier Board ALPS Tuning Deluxe Edition Product Description: The headphone amplifier adopts NE5534 dual op amp integrated circuit with RC original. TPA6120A is a stereo ADC with 216KHZ sampling frequency 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 600Ω Power; current feedback architecture; dynamic range greater than 120dB; SNR is 120dB; output noise is 5μV when gain 2V/V; 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 main circuit of electrolytic capacitor signal adopts Siemens, and the main filter capacitor adopts the capacity of Nikon 2×3300UF to ensure strong and continuous power support. 3. The resistance uses five-ring metal resistors, and the main circuit uses five-ring metal film resistors with an accuracy of ±1% to ensure 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 full tinning process 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, very quiet. 6. Use UPC1237 and Hongfa relay for output delay protection 7. Use ALPS 27 sealed potentiometer imported from Japan (one potentiometer costs tens of yuan) 8. The two red switches are the gain switches of the corresponding channel Package: 1PCS TPA6120A Headphone Amplifier Board ALPS Tuning Deluxe Edition Payment Method: PayPal preferred Shippment:1.
