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/a??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. Performance (<0.03% THD) and power efficiency of Class D amplifier. Its SNR is greater than 100dB, PSRR is 80dB, the efficiency of the power stage is as high as 88%.
Features: -Using original TAS5630, OPA1632DR, TL072 -Main electrolytic capacitors with three battalions brand, capacity 470UF / 100V * 4, to ensure strong support for a steady stream of power. -Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio. -Using fully shielded high-current inductors, to ensure crisp and powerful sound. -1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.
