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 drivers, this application is optimized for the characteristics of OPA1632 Excellent gain bandwidth of 180MHz 50V/┢s and very fast conversion rate, producing very low distortion 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 can easily achieve single-ended full differential output conversion. Differential output reduces even harmonics and reduces common mode noise interference.
OPA1632 provides excellent performance ADCs high-performance audio PCM1804. The driver, such as the shutdown function is also enhanced when used TI’s TAS5630 is a Class D amplifier with integrated analog input 300W stereo (total power 600W), which can provide up to 300W stereo from a single power supply 50V to 4 ohm speakers, with the traditional class AB amplifier.
