THS4012 Dual Channel High Speed Operational Amplifier 290M Voltage Feedback Amplifier Module

THS4012 Dual Channel High Speed Operational Amplifier 290M Voltage Feedback Amplifier Module

Description:
- This module is a dual channel amplifier designed for SOP-8. The function of the amplifier module is highly compatible with the chip model. It is basically applicable to most of the SOP8 series dual op amp chips on the market, and is very convenient to use. The input and output of signals are all coaxial SMA high-frequency connectors, which can reduce the loss amplitude of signals and shield the interference of other signals. At the same time, the on-board circuit can be changed into in-phase, reverse phase, cascade and other functions according to the needs of users. The module uses in-phase proportional amplification circuit, and the on-board variable manual potentiometer is used to adjust the amplification. The PCB board is compatible with the RF type dual op amp. The routing and design are in accordance with the RF wiring standards, and is compatible with low-frequency signals. Modules are both functional and practical after a lot of chip verification and practice.

Note:
- The module power supply is dual power supply, and the voltage cannot exceed ± 16V.
- Since the module is a high-precision device, in order to avoid unnecessary interference linear power supply is recommended.
- It is recommended to use good wire to input and output signals, and use an oscilloscope to observe the effect. Poor contact or poor-quality wire may cause signal attenuation or excessive noise.
