1200W TAS5630 Amplifier OPA1632 Fully Differential Amplifier Class D 2.0 High Power Digital Power Amplifier Board
Product Description
OPA1632 is a fully differential amplifier used to drive high-performance audio analog-to-digital conversions (ADCs). The highest audio quality, it provides very low noise and output driver, this application is optimized for the characteristics of OPA1632 Excellent gain bandwidth of 180MHz 50V/μs and very fast conversion rate, resulting in very low distortion of 0.000022%. Very low input noise of 1.3nV/√Hz further ensures the maximum signal-to-noise ratio and dynamic range. Fully differential The flexibility of the structure makes it easy to achieve single-ended fully differential output conversion. The differential output reduces even harmonics and reduces common mode noise interference. OPA1632 provides ADCs with excellent performance and high-performance audio PCM1804. The driver, such as the shutdown function when used, is also enhanced To increase the flexibility of the amplifier. TI's TAS5630 is a 300W stereo (total power 600W) class D amplifier with integrated feedback analog input, which can provide up to 300W stereo from a single power supply of 50V to a 4 ohm speaker, with a traditional class AB amplifier Performance (<0.03% THD) and power efficiency of a Class D amplifier. Its SNR is greater than 100dB, PSRR is 80dB, and the power stage efficiency is as high as 88%. TI's industry's highest power Class D amplifier
Title goes here.
1，Use original TAS5630, OPA1632DR 2，The main filter electrolytic capacitor adopts a capacity of 470UF/100V*8 to ensure strong and continuous power support. 3，The resistance uses five-ring metal resistors, and the main circuit uses five-ring metal film resistors with an accuracy of ±1% to ensure a good signal-to-noise ratio of the whole machine. 4，The red-grey ring audio special high-current inductor is used to ensure the sound is clear and powerful. 5，PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.

Note
The OPA1632 produced by TI is not the JRC5532 used by other businesses. The price difference is very big. When using it to form a differential amplifier, not only the input end is a differential input, the output end is also a differential output, so such an amplifier is called It is a complete differential amplifier.
