D5p DAC Headphone Amplifier ES9038 Decoder For XMOS Bluetooth CPLD Coaxial Optic Fiber Aptx DSD

D5p DAC Headphone Amplifier ES9038 Decoder For XMOS Bluetooth CPLD Coaxial Optic Fiber Aptx DSD

D5p Headphone Amplifier:
- Chip: Single ES9038Q2M
- Bluetooth: 64215
- USB: Italian interface (Can be replaced for XMOS)
- CPLD + Split OP BUFF headphone amp
- Including power supply, antenna (One-piece hollowed out aluminum housing)

Description:
This is a cost-effective mini headphone amplifier DAC based on ES9038Q2M. The shell is made of a whole piece of pure aluminum alloy processed by CNC, with a simple appearance and rich functions. Small size but with big driving force. With a 0.96-inch OLED screen, the parameters are clear at a glance. Various filters can be set freely. Added self-developed FPGA clock management, jitter elimination technology, POP sound elimination technology, with technology unique to high-end products, supports Dop128, and can support PCM768kHz DSD512.

Size: 125mm*100mm*25mm(L*W*H), the size of a palm.
Thrust: It adopts OP + Buffer solution to easily deal with high resistance headphones.
Performance: It adopts self-developed CPLD clock reforming technology.
Function: It integrates USB, coaxial, optical fiber, and Bluetooth input, breaking the volume limit and adding a high-thrust headphone amplifier circuit.
The design of the amp DC detection and protection circuit ensures the safety of the headset.

Sampling Rate:
- USB PCM 16-32bit, 44.1-384kHz DSD DSD64-DSD256
- COAX PCM16-32bit, 44.1-384kHz DSD Dop64-dop128
- OPT PCM 16-24bit, 44.1-192kHz DSD Dop64
- Bluetooth PCM 44.1-48kHz

Other Parameters:
- Power supply voltage: DC12V
- Power supply current: 280ma
- Machine net weight: 356g
- Distortion: THD+N<0.001%
- Size: 125mm*100mm*25mm

More Details:
- The I/V conversion circuit adopts high-performance, high-speed, low-distortion audio op amp OPA1612A, which ensures the instantaneous response and high resolution of the sound. The performance and parameters of the passive IV circuit composed of resistors are much better
- Taiwan-made gold-plated RCA sockets
- Use American low temperature drift and low jitter silicon crystal oscillator for Sitime
- Audio capacitor made of COG material for Murata to ensure sound quality
- High-precision low-temperature resistors (25ppm 1% accuracy) effectively ensure the consistency of the left and right channel parameters and performance, and eliminates the impact of temperature changes on performance
- Using 5pcs LP5907MFX ultra-low ripple LDO, power supply noise <10uVrms, power supply rejection ratio of 82dB
- Black gold-plated PCB and reasonable layout routing

Package Included:
- 1 x Set of DAC Headphone Amp

Note:
- It is assembled.
- It is recommended to use with linear power supply.
