IWISTAO 300W+300W TAS5630 Amplifier Board Stereo Audio Class D Digital OPA1632 Preamp PCBA HIFI DIY
Model No: WTAS5630
OPA1632 is a fully differential amplifier for driving high performance audio analog-to-digital conversion (ADCs). As the highest audio quality, it provided very low noise and output driver. optimized for this application and the characteristics of design excellent the gain bandwidth of OPA1632 is 180MHz 50V/ μ s and has very fast conversion speed, and its input noise is 1.3nV/√Hz that ensure the performances of S/N ratio and dynamic range, and its distortion is very low, only 0.000022%. With fully differential structure flexibility, it can be easily implemented the single end fully differential output conversion. The differential output to reduce even harmonics, provides ADCs for high performance audio PCM1804. Excellent performance of the drive to reduce common mode noise OPA1632 interference, such as the use of stop function also enhances the flexibility of the amplifier.
TAS5630 of TI company is class D amplifier that integrated analog input 300W stereo feedback (total power 600W) , it can provide up to 300W stereo from single supply 50V to 4 ohm speaker, its performance combine traditional class AB amplifier (<0.03% THD) and efficiency of powerful class D amplifier. Its SNR is greater than 100dB; PSRR is 80dB, and efficiency is up to88%.
