HDAM fully discrete dual op amps, based on the Marantz HDAM circuit. The input uses the warmest field effect tube precision pairing. Previously, because of the large number of components, it can only be used in the discrete pre-stage. The board is very large. Design, the bottom area is almost the same as dual op amps, the pins are familiar with OPA2604AP NE5532 MUSES02 OPA2604 LME49720HA LME49720HA OPA2107AP AD827SQ / 883B and so on! ! The new upgraded version of the op amp emperor is fully balanced, the sound bottom is clean, natural listening, high analysis, dynamic, low-frequency dive deep, mid-range full, warm and mellow vocal sweet moist, high-frequency transparent, delicate and supple. 1. There is no relatively low open-loop gain, so no deep negative feedback like the op amp is needed, and the sound comes out more naturally and delicately 2. Wide voltage application range: excellent operation in positive and negative 4V to positive and negative 18V voltage 3. Larger output current, the output current of general op amp is about 40MA, the maximum output current of this op amp is 50MA
This op amp is suitable for fever audio amplifier, pre-amplifier, CD, amp, audio amplification, DAC output buffer, low-pass filter, buffer. And precision instruments, fast data acquisition, DAC output amplification, optoelectronics, ultrasound, sonar, high impedance sensor amplifiers, high performance audio circuits, active filters.
