Description
120 dB OPA627 High Performance Precision High Speed Difet Operational Amplifier High Impedance Universal Amplifier
Product Description
This module is a single-channel amplifier module designed for SOP-8 package single op amp. The module function and chip model are highly compatible. It is basically suitable for most SOP8 series single op amp chips on the market, and it is very convenient to use. The input and output of the signal adopts coaxial SMA high-frequency connectors, which can reduce the loss of the signal and shield the interference of other signals. At the same time, the on-board circuit can be changed to in-phase, reverse phase, follow, integral and transimpedance functions according to user needs , The module uses the same phase amplifier circuit, and uses the on-board variable manual potentiometer to adjust the magnification. The PCB board is compatible with single-op amps of radio frequency. The wiring and design are in accordance with radio frequency wiring standards, and it is compatible with low frequency signals. No matter in function or practicality, the module has been verified and practiced by a large number of chips.

Installation Instructions
Precautions for module use
(1)-The power supply of the module is a dual power supply, and the voltage cannot exceed ±18V. (2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use linear Power supply. (3) For the output signal, it is recommended to use a good wire for input and output signals. Use an oscilloscope to observe the effect. Poor contact or poor quality wire may cause signal attenuation or excessive noise.
FAQ
Q: How can I confirm whether my chip is compatible with this board? A: You can see if the pins in the chip data are consistent with the key position labels of the module chip, and you can replace them if they are the same. Q: My signal is tested with an oscilloscope and there is no problem. What happens when the amplitude of the access module port becomes smaller? A: Generally due to impedance problems, the input impedance of the module is 1KQ. If your signal output capacity is not enough, it will be pulled down, or the input impedance configuration resistance of the module will be increased. Q: The module has positive and negative power supply, the input frequency is 100K, and the amplified output is a triangle wave? A: Because it is a low-speed amplifier, the gain-bandwidth product is limited. Generally, reduced magnification or waveform distortion may be caused by insufficient gain-bandwidth product. You can try to replace a higher bandwidth op amp.
