It is an upgraded version of OPA627 Operational Amplifier.
It combines high speed with high DC precision and high AC performance.
The operational amplifier achieves low offset voltage (50μV), low temperature drift (0.45μV/℃ typical value), low bias current (1pA typical value), and low noise (4nV/√Hz typical value), with noise of only 60nVRMS 0.1Hz to 10Hz.
Operating in a wide power supply voltage range of ±4V to ±18V, the power supply current per channel is only 5.5mA(typical value).
Sound quality is more transparent than classic high-end OPA627. Very penetrating, medium frequency is also very delicate and non-burr, it is very worth using for new machines and grinders.
It can replace For NE5532 MUSES8920, OPA2604 LME49720, OP275, AD827, etc.
