Support is limited to customers who have already adopted these products.
The μPC4570MF-DAA is an ultra low-noise, wideband high slew-rate, dual operational amplifier. Input equivalent noise is three times better than the conventional μPC4558 type op-amps. The gain bandwidth products and the slew-rate are seven times better than μPC4558. In spite of fast AC performance, the μPC4570MF-DAA is extremely stable under voltage-follower circuit conditions. Supply current is also improved compared with conventional wideband op-amps. The μPC4570MF-DAA is an excellent choice for pre-amplifiers and active filters in audio, instrumentation, and communication circuits.
