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/┢s and very fast slew 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 during use, 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 (
