I will design low noise audio pcb layout amplifier schematic hi fi dac for audio device

Troubled by ground hum, power hiss, or audio crosstalk? I deliver low-noise audio PCB layout, schematic capture, and Hi-Fi analog circuit design for amplifiers, DACs, preamps, and DSP processors.

WHAT I OFFER & DESIGN SERVICES:

• Low-noise audio PCB layout & schematic design in Altium, KiCad, & EasyEDA

• Star ground topology, ground loop isolation, & zero-hum plane separation

• High-performance audio DAC layout (ESS Sabre, AKM, TI Burr-Brown)

• Power amplifier circuits: Class-D, Class-AB, TPA3116, TPA3255, & Discrete Op-Amps

• Low-noise power supplies: LDO filtering, LC ripple suppression, & AGND/DGND splits

• Preamps, active crossovers, headphone amps, & XLR balanced audio paths

• Bluetooth 5.0/5.3 Hi-Fi audio integration (aptX HD, LDAC) & USB-C DAC routing

• High Signal-to-Noise Ratio (SNR) routing, differential trace matching, & shielding

• Thermal relief design, copper pour heatsinks, & impedance control

• Production deliverables: Gerber (RS-274X), NC Drill, BOM, CPL, & 3D STEP

I guarantee 100% manufacturing readiness for JLCPCB, PCBWay, and global board houses.
