HiFi Discrete Single/Dual Op Amp Class A Module Chip NE5534/OPA627/604/SS3601

Item description

Warm Tips

  • To give the full effect of this discrete op-amp, it is recommended that the power supply current of a single op-amp be more than 100mA, and that of dual op-amps should be more than 200mA.

Features

  • The Class A fully discrete op-amp is designed for professional audio applications, meeting users' needs for low noise, low distortion, and high linearity without coloration.
  • Using a high-performance temperature-stabilized power supply independent current source. The independent current source will be locked at the optimum operating point regardless of supply voltage or temperature.
  • The current structure adopts 5 pairs of low-error SMD triodes with twin tubes, multiple precision triodes are paired, and the output uses 1 pair of medium power to amplify the current of the tubes. The noise is less than 500 nv/rms (2.9 nv√HZ) @20Khz, and the output current can be up to 65mA.
  • The overall sound field is wide and full, with distinct layers, clear mid-frequency brightness, high density, deep and flexible low-frequency dive, suitable for a variety of audio amplifiers.
  • Applies to:
    Low Impedance Line Amplifiers and Drivers
    Active Filters and Equalizers
    Summing/Mixing Amplifiers
    High-Performance Microphone Preamps
    High-performance A/D and D/A front-end preamplifiers
    High Current Buffer Amplifier
    High-Performance D/A I-V Converter
