Комментарии об отличиях

AK4490 ↔ ES9018K2M

AK4490: 32-bit 2ch DAC, Velvet Sound architecture, DSD 11.2MHz / PCM 768kHz, 120dB SNR, THD+N -108dB, 5V analog / 3.3V digital, digital filter с selectable sound color (Sharp/Slow/Short/Low-dispersion), QFN-32. ES9018K2M: 32-bit 8ch mobile DAC, HyperStream II architecture, DSD 11.2MHz / PCM 384kHz, 129dB SNR (mono), THD+N -120dB, integrated I/V conversion, I2C control. Отличия: AK4490 — 2-channel dedicated Hi-Fi DAC с extensive digital filter options, ES9018K2M — 8-channel mobile DAC (can be configured as 2ch). AK4490 поддерживает fully differential output (внешний I/V), ES9018K2M имеет встроенный I/V converter. У AK4490 встроенный OSRD (Over Sampling Ratio Doubler) для DSD, у ES9018K2M — DSD native support. Цифровой фильтр: AK4490 имеет 5 selectable filters, ES9018K2M — minimal phase + fast/slow roll-off. I2C: AK4490 нет, управление pin-based; ES9018K2M — I2C required для конфигурации. Power: AK4490 требует ±5V analog, ES9018K2M 1.2V/3.3V. Критично: разные требования к power supply и обвязке.
