NEW Class D TAS5613 2.1 Digital Power Amplifier Board OPA1632DR, TL072 75W + 2 * 150W DC36V customize

TAS5613 2.1 digital power amplifier board Class D 75W + 2*150W(4 Ohm), beyond TPA3116 LM1875

 

Product introduction 

 

 

OPA1632 is a fully differential amplifier is used to drive high performance audio analog - to - digital conversion (ADCs). The highest audio quality, which provides a very low noise and output driver, the characteristics of this application is optimized designed OPA1632 excellent gain bandwidth of 180 MHZ 50 v/u s and very fast conversion speed, produce very low distortion by 0.000022% for 1.3 Hz nV /) to very low input noise further ensure the maximum signal - to - noise ratio and dynamic range. The difference of the structure of the flexibility, can easily realize the single-ended fully-differential output conversion. The differential output lower harmonics, reduce common-mode noise interference OPA1632 provides good performance of high performance audio PCM1804 ADCs. Drive, such as using the stop function is to enhance the flexibility of the amplifier. The TAS5613 of TI company is integrated with the feedback of the analog input 150 w stereo (total power 300 w) class D amplifier, can from a single power supply 36 v to 4 ohm stereo speakers to provide up to 150 w, the performance of traditional class AB amplifier (< 0.03% THD) and power efficiency of class D amplifier. Its SNR is greater than 100 db, PSRR is 80 db, the efficiency of the power level is as high as 88%, Texas instruments (TI industry the highest power of class D amplifier
