Description Raspberry Pi HiFi DAC Pro Hat ES9038Q2M Audio Card PCM DSD Lossless High Resolution Digital-to-Analog Converter Adapter for Raspberry Pi 4 3B 3B Zero w Zero Product Description InnoMaker HiFi DAC Pro Hat This Hat is based on a high performance audio DAC chip ES9038Q2M. The ES9038Q2M handles up to 32-bit/384kHz(PCM), DSD256 and DSD512 data in master or slave timing modes. It use the critically acclaimed ESS patented 32-bit HyperStream II DAC architecture and Time Domain Jitter Eliminator and delivers a DNR of up to 129dB and THD N of -120db, a performance level that will satisfy the most demanding audio enthusiasts. On-board two low jitter oscillators(45.158M and 49.152M) to support ES9038Q2M master mode, support more exact sample rate clocks of ES9038Q2M. Different from other DAC hat that forced user to use the IIS master clocks from Raspberry Pi which comes with a lot of jitter, just for save cost and design time. On-board three Texas Instruments SoundPlus High-Fidelity Audio Operational Amplifier, afford 2.1vrms output. The best output level for most of device. A lot of high-end music mobile phone, digital music players, digital music workstations were based on the ES9038Q2M chips and same designed. So we are very pleasure to take it to the Raspberry Pi player. No soldering, no additional cables. Just plug it in and do some simple configuration, You can get a same high-class low-cost music player.
