Dear customer friend:
Thank you very much to choose the SHENZHEN SMSL Electronics Co., Ltd. sApII PRO TPA6120A2 Big Power High Fidelity Stereo Headphone Amplifier

Our company is a professional Digital Amplifier / MINI DAC/Headphone Amplifier manufacturers.

Strong team, professional skills, integrity services, it is our aim.

 

TPA6120A2 is TI (Texas Instruments) has introduced the current feedback differential input high-fidelity headphone amplifier IC.

DESCRIPTION

TPA6120A2 is a high fidelity audio amplifier built on a current-feedback architecture. This high bandwidth, extremely low noise device is ideal for high performance equipment. The better than 120 dB of dynamic range exceeds the capabilities of the human ear, ensuring that nothing audible is lost due to the amplifier. The solid design and performance of the TPA6120A2 ensures that music, not the amplifier, is heard.


It can work with:

Sennheiser: HD598/HD600/HD650/HD800 ......

Beyerdynamic: T1/T5P/DT880/DT990 .....

AKG: K701/Q701/K702 .......

GRADO: SR80I/SR225I/SR325 .......


1:
sApII PRO circuit design as Texas Instruments (TI) top-TPA6120A2 headphone driver chip as core, TPA6120A2 is a current feedback amplifier circuit, conversion rates up 1300V/μs. Distortion of only 0.00014% THD + N, 120dB dynamic range, 120dB SNR. TPA6120A2 very powerful driving force, the maximum output current up to 700mA. Meet the large impedance headphones. With see above indicators, TPA6120A2 is positioned as HI-FI TI class headphone amplifier chip.

Therefore, sApII positioned as a professional high-power headphone amplifier.

2:
sApII PRO circuit design as a front end to Burr Brown OPA2604AP enlarge.
OPA2604AP for high-performance audio system design special op amp。low harmonic distortion, low noise, high gain bandwidth characteristics.
Dual FET-input OPA2604 provides a wider dynamic range, the sound is more resistant to listen. Generally used in professional audio equipment, spectrum analyzers and other high-end devices. (Old version without this part circuit)

3:
sApII PRO use Texas Instruments (TI) high-performance op amp NE5534 as headphone protection circuit, high sensitivity headphones starting voltage protection circuit protection is 0.7V, than ordinary amp protection circuit sensitivity doubled. Protect your headphones, we are more professional. (Earlier versions do not have this part circuit)

4:
sApII PRO power supply using partial pressure techniques,Use high precision potentiometers for balance calibration, a high degree of positive and negative voltage balance. Another specialized high capacity filter capacitor filter, power quite clean. Maximum inhibition of low-noise, so that the headset can be heard almost no noise, let your ears more comfortable.
