Hifi OP03 Full Discrete Component Field Effect Input Dual Op Amp Module

Description: Description: Upgrade DAC, pre-level, decoding, amp must be necessary Class A amplifier circuit, a class to enlarge the big distortion, sound sweet and sweet. Can replace NE5532, LME49720HA, AD827, OPA2604, OPA2111, JRC4558 and other dual op amp Size 30X40X26, pin part height 10MM Can be used in the state of 1 times the gain (voltage follower), open loop gain, closed-loop stability, suitable for a variety of occasions to replace the general op amp, such as IV conversion, pre-amplification, active filtering, performance. Op amp module and the general opener difference: 1. Transposition module Each stage of the transistor works in Class A, greatly reducing distortion and improving sound density. While the general op amp current is very small, not working in a class. 2. Transposition module transistor through precision matching, better performance, more accurate work, and the general operation by the production process limit, it is impossible to each pair of transistors are paired. 3. Operational amplifier output current capacity, the working voltage can go to plus or minus 50V, the output impedance is low. General op amp current output capacity is limited, the operating voltage is low. 4. The op amp module circuit is more concise, the circuit has been optimized to let the performance of the op amp module to the fullest, while maintaining the characteristics of harmonious and resistant. The general opener usually can not maintain the high density and the two advantages of hearing, or high density, high and low sound, but intolerable, or Naiting, but the density is low, weak resolution. This is the op amp by the production process and circuit design constraints, and the op amp module optimization circuit, artificial matching transistor, so that it not only has good performance, but also harmonious and resistant to achieve the indicators to enhance. For CD machine IV conversion, analog amplification and other places, direct replacement of the general dual op amp, the effect is greatly improved. Low-frequency thicker and more powerful deep, high frequency is also scattered, the continuity of the sound than the average op amp greatly improved, it sounds like a real simulation of taste Europe and the United States taste design, intermediate frequency and density first class. The op amp for the thick sound type, bass thickness than the average opener thick, and a stronger sense of music. A lot of valuable decoding sound is not the secret op amp, with discrete components output. Jie Ming op amp module just to meet your needs, so that the quality of the decoding better sound. FET input, double differential circuit, tube output. General opener internal pairing is bad, by the high open-loop gain to maintain stability, and op amp module parts selection is strictly a lot, the current accuracy is also high, so in exchange for extraordinary sound quality. Transistor precision matching, fever parts, free ground wire, direct substitution, very stable. Used in the CD machine IV conversion part and low-pass filter part, CD machine sound more mellow, and very Naiting, in exchange for the ordinary op amp will feel dull, the sound thinner The output current is much larger than the average op amp, the maximum output current of more than 200MA, can directly drive the headset, the sound is also very beautiful Using imported transistors, the United States fever resistance production, gold-plated pin. Now there is a module selection: 1.OP01, imitation will be grass module, sweet sound; Operating voltage: 5V-30V Maximum output current: 200MA Input impedance: 1M Frequency response: 0-200KHZPackage Included:1 x HIFI Fever OP03 Full Discrete Component Field Effect Input Dual Op Amp Module Payment We accept PayPal only.We only ship item to your PayPal verified address.Payment must be received within 3 days from the date of purchase.Orders will be processed and dispatched within 3 days normally Terms Of Sales 1.
