product details:
The OPA1632 is a fully differential amplifier designed to drive high-performance audio analog-to-digital conversion (ADCS.)
The highest audio quality, which provides very low noise and output drivers,
this application is optimized for the design of the OPA1632 Excellent gain bandwidth of 180MHz 50V / and very fast slew rate,
resulting in very low distortion 0.000022%. Input noise is very low 1.3nV / Hz further ensures maximum signal-to-noise ratio and dynamic range.
The flexibility of the structure allows for easy implementation of single-ended fully differential output conversion.
Differential output reduces even harmonics and reduces common mode noise interference The OPA1632 provides excellent performance for ADCS high performance audio PCM1804.
The drive is also enhanced if used The flexibility of the amplifier, the TAS5613A,
is a high performance analog input Class D medium power amplifier with integrated closed loop feedback technology (PurePath HD).
It&39;s driving capacity up to 150W. The output power level depends on the thermal configuration of the target application.
High-performance thermal interface materials should be used between the exposed exposed heat sinks and heat sinks to achieve high output power levels.
36 V single power supply, 4 ohm load speakers provide stereo output 150W + 150W.
-using the original TAS5613, OPA1632DR
-main filter electrolytic capacitor imported three Ying brand 470UF * 4 / 100V, to ensure a steady stream of dynamic support.
-resistance selection of five-ring metal resistance, the main circuit with a precision of 1% of the five-ring metal film resistors to ensure a good signal to noise ratio.
-use of audio dedicated high current inductor to ensure that the sound crisp and powerful.
-PCB with 1.6mm thick double-sided sheet, 2.0 oz copper thick, spray tin all the process to ensure the size of the current through the performance. First-class PCB quality.
