Nisshinbo Micro Devices NL8902

The NL8902 is a high-quality dual audio operational amplifier incorporating advanced “MUSES” audio technology. We have applied the high quality sound technology to provide an excellent balance of sound quality, characteristics, and price. Designed for superior audio fidelity, the NL8902 offers exceptional low-noise performance with a voltage noise density of just 10 nV/√Hz at 1 kHz, and impressively low distortion at 0.0004% at the same frequency. The amplifier achieves a high slew rate of 20 V/µs and a gain bandwidth product of 9 MHz, ensuring accurate and responsive audio reproduction across various frequencies. With JFET input technology, the NL8902 features an extremely low input bias current of 10 pA, making it particularly suitable for sensitive audio applications such as preamplifiers, active filters, line amplifiers, and I/V conversion amplifiers. Moreover, the NL8902 demonstrates outstanding electromagnetic interference (EMI) immunity, quantified by an EMI rejection ratio (EMIRR) of 82 dB at 1.8 GHz, ensuring stable performance in electrically noisy environments. It operates within a versatile voltage range from ±4.0 V to ±16 V, and maintains operation without phase reversal throughout the input voltage range, enhancing its reliability in audio system designs.
