Product introduction
OPA828 Super Op Amp, distortion of 2.8 parts per million. OPA828 chip is single op amp. Single to double, each PCB contains 2 chips.
Model interpretation
K:K series, only output pin is precious metals (Platinum, Gold, Palladium, Iridium) Q: Q series, 8 PCS pin all are precious metals (Platinum, Gold, Palladium, Iridium) PTD:Platinum AUD:Gold PDD:Palladium IrD:Iridium
Sound Description·
5U gold-plated version: clear and high resolution, strong low-frequency force more than OPA827, good elasticity, texture and volume are better than 627AU, and the midrange is sweeter; The high frequency is clearer than the 0PA827, and the high frequency detail and extension are much greater. Beryllium copper version: Three paragraphs are more balanced, improving the level of detail. PTD version: The sound is high-frequency and cohesive. AUD version: sweet and supple, slightly slower, low frequency fluffy. PDD version: rigorous and professional sound, strong low frequency, enough power. IrD version: high density, extended at both ends, ultra-rich high-frequency detail with characteristics. Precious metal needles all improve cohesion, density, thickness, high frequency.
The OPA828 is the best voltage single op amp available. Voltage-type op amp with current-type speed. Super op amp, ultra-high performance JFET input precision, wideband, high-speed single op amp. The leader in the next generation of op amps. OPA828 input voltage noise density of 4nV///Hz at 1kHz exceeds OPA627, GBW=45MHz, SR=150V/¥ìs, ±4V to ±18V, input offset voltage 50¥ìv, input offset current 1pa, total harmonic distortion 2.8 per 10 million, JFET input timbre is pleasant. Officially recommended IV conversion, active filter, high impedance amplification, unity gain stability. This product has high clarity, and the capacitor needs to be warmer. This op amp belongs to a high-speed broadband op amp, requiring decoupling must be set according to the specification, no sound after plugging, noise, is caused by poor decoupling, in the op amp 4, 8 pins to ground and 0.1uF film can be solved.
