TPA6120A ear clip board (Deluxe Edition)

Product Introduction

the ear clip uses NE5534 dual operational amplifier integrated circuit with resistance original, TPA6120A is TI launch dynamic range124DB signal-to-noise ratio216kHz sampling frequency stereo ADC80MW power is provided to 600Ω by using a ± 12V voltage when the (THD + N) is%; Current feedback architecture; Dynamic range is greater than 120dB;SNR is 120dB; the output noise at the gain of 2 V/V is 5μv; Operating voltage range: ± 5 ~ ± 15V; Conversion rate: 1300V/μs; Differential input; separate power supply for low crosstalk; Short circuit and thermal protection

product Details

1. Adopt original Toshiba TPA6120A and ne5534.

2. The main circuit of electrolytic capacitor signal adopts Siemens, the main filter capacitor adopts the capacity Nikon 2 × 3300UF to ensure strong continuous power support.

3. Five-Ring metal resistor is selected for resistance, and precision is adopted for main circuit± 1% the five-ring metal film resistance ensures a good signal-to-noise ratio of the whole machine.

4. PCB1.6 MM thick double sided plate, 2.0 oz copper thickness, full process of tin spraying, ensuring good passing performance of large and small current. PCB quality.

5. The wiring layout of the whole circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts a one-point grounding method. Carry headphones in the dead of night almost can't hear the noise, very quiet.

.

6. Use UPC1237 and Hongfa relay for output delay protection

.

7. Imported from Japan ALPS 27-type sealed potentiometer (a potentiometer costs tens of yuan)

8. The two red switches are the gain switches of the corresponding channel.
