OP03 is a discrete op amp with classic plug-in components, OP01 is a discrete op amp with chip components, the circuits of the two are different
OP03, imitating sbigrass module, plug-in components, sweet tone
OP01, imitation car guy module, SMD components, smaller volume, mellow tone
Single op amp module volume 36*22*12MM (including pin part), pin part height 5MM
OP03 adds a midpoint adjustable potentiometer, which is not installed by default, and can be installed if needed
Field effect tube input, double differential circuit, pair tube output
Used in CD player IV conversion, analog amplification and other places, instead of general op amp, the effect is greatly improved.
The transistors are precisely matched, fever parts, no external grounding wire, direct replacement, very stable.
The output current is much larger than that of general operation. The output current is more than 200MA, which can directly drive the earphones, and the sound is also very beautiful.
European delicious design, medium frequency and density
Neutral tone, high resolution, tuning style similar to vinyl, thick warmth and delicate
It can work in the state of 1x gain (voltage follower), with large open loop gain and stable closed loop. It is suitable for various occasions to replace general op amps, such as IV conversion, pre-amplification, active filtering, etc., to improve op amps performance.
Class A amplifier circuit, Class A amplifier greatly reduces distortion, and the sound is mellow and sweet.
Can replace NE5534, AD797, AD843, OPA604, OPA627 and other single op amps
It can be lengthened with an extension cord without being restricted by volume.
Upgrade DAC, preamp, decoding, amp must
Output current: 200MA
Input impedance: 1M
Frequency response: 0-200KHZ
