1. OPA1632 is a fully differential amplifier used to drive high-performance audio analog-to-digital conversion (ADCs). With the highest audio quality, it provides a very low noise and output driver.
2. The application program has optimized the characteristics of opa1632, which has excellent gain bandwidth of 180mhz 50V /us and very fast conversion rate, resulting in very low distortion of 0.000022%.
3. A very low input noise of 1.3nv/hz further ensures the maximum signal to noise ratio and dynamic range. With the flexibility of fully differential structure, it is easy to realize single end full differential output conversion. Differential output reduces even harmonics and common mode noise interference.
4. OPA1632 provides the driver of high-performance audio pcm1804 of ADCs with excellent performance. If it is used, the shutdown function also enhances the flexibility of the amplifier.
5. TAS5630 of TI company is a class D amplifier integrated with feedback analog input 300W stereo (total power 600W), which can provide up to 300W stereo from single power 50V to 4 ohm speaker.
6. It has the performance of traditional class AB amplifier (< 0.03% THD) and class D amplifier Its SNR is more than 100dB, PSRR is 80dB, efficiency of power level is as high as 88%, the highest power class D amplifier in Ti industry of Texas Instruments.
1. Using original TAS5630, OPA1632DR, TL072.
2. Main electrolytic capacitors use capacity 470UF / 100V * 4, to ensure strong support for a steady stream of power.
3. Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
4. Using fully shielded high-current inductors, to ensure crisp and powerful sound.
