TPA6120A NE5534 AC 220V ADC HIFI Stereo Headphone Amplifier Earphone Amp
- Amp applies NE5534 that is dual operational amplifier integrated circuit with resistive and capacitive components. TPA6120A, has the maximum dynamic range 124DB and the signal-to-noise ratio that is 216KHZ, the frequency stereo ADC. When (THD + n) is 0.00014% , use voltage a + 12V and power 80mW to 600 ohm; current feedback architecture; dynamic range is more than 120dB; SNR is 120dB; When the gain is 2V/V, the output noise is 5muon V; operating voltage range:- + 5 to -+ 15V; conversion rate: 1300V/ [mu] s; differential input; separate power to get low crosstalk; short circuit and thermal protection
- Apply TPA6120A and NE5534.
- The main circuit of electrolytic capacitor signal is the famous brand, the main filter capacitor use capacity Nikon 2 x 3300UF, to ensure a steady flow of power support.
- Resistance is the five rings of metal resistance, the main loop with the accuracy of 1% of the five ring metal film resistors, to ensure good overall signal to noise ratio.
- PCB uses 1.6mm thick double-sided board, 2 an ounce of copper thickness, spray tin all process, to ensure the size of the current good through performance. First class PCB quality.
- The whole circuit board layout is quite strict and reasonable, the overall PCB take a little grounding line. Hardly what noise at night when carrying Headset, very quiet.
- UPC1237 and relay protection Acer output delay
