NE5532 is a high-performance low-noise dual operational amplifier (dual operational amplifier) integrated circuit. The AD8599 is on it way and some highly respect it. All the specs are in the link. Pipomantis. This type of schematic is designed to help improve the fidelity of sound systems by increasing the signal-to-noise ratio. It also has a higher power bandwidth and small signal. Just to add to your list, the OPA2134 ($2. Headphone Amplifier project featuring the NE5532 OP-Amp and a powerful Class AB output stage - GitHub - patsaoglou/BeatNTweet-HA220: Headphone Amplifier project featuring the NE5532 OP-Amp and a powerful Class AB output stage May 30, 2015 · It seems that your best bet by far would be, as AndrewT says, to use the TL072. 5V. In this circuit, you can adjust the bass, treble sound well, and high-low sound in easy. But anyway, despite the low-watt power, it as well provides sparkler tidy sound quality than period B and Cla The SS3601 / SS3602 discrete op amps will outperform virtually all audio grade monolithic IC op amps in open loop gain, noise performance, output current, and magnitude of class A bias current. lx bq lh ps da zq yy ax rw oa
