HIFI Audio Low Noise Precision Fully Discrete Class A Single Dual Op Amp
Upgrade NE5534/OPA627/604/SS3601/2604 For DAC Preamp Amplifier
Description:
1> This class-A full discrete op amp refers to Burson Audio, Sparkos lab, Jensen and other imported high-end precision discrete op amps. It is specially designed for professional audio applications and fields that require low noise, low distortion and high linearity without coloration.
2> The noise is lower than 500 nv/rms (2.9 nv√HZ) @20Khz, and the output current can be up to 65mA.
3> The current structure adopts 5 pairs of twin tube low-error SMD triodes, multiple precision triodes are paired, and the output uses 1 pair of medium power tubes to amplify the current.
4> The overall sound field is wide and full, the scene is grand, the layers are clear, the mid-frequency brightness is clear, the density is high, and the low-frequency dive is deep and flexible.
5> A high-performance temperature-stabilized power-independent current source is used, which allows the bias to remain locked at the optimal operating point regardless of supply voltage or temperature.
Application:
1> Low impedance circuit amplifiers and drivers
2> Active filters and equalizers
3> Summing/Mixing Amplifier
4> High performance microphone preamplifier
5> High-performance A/D and D/A front-end preamplifiers
6> High current buffer amplifier
7> High performance D/A I-V converter
