It is basically applicable to most SOP8 series dual operational amplifier chips on the market, and is very convenient to use. The input and output of the signal are all coaxial SMA high-frequency connectors, which can reduce the loss amplitude of the signal 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 user's needs. The module uses the in-phase proportional amplification circuit, and uses the on-board transformer manual potentiometer to adjust the amplification factor. The PCB board is compatible with RF dual operational amplifiers. The routing and design are in accordance with RF wiring standards, and is compatible with low-frequency signals. Both in terms of function and practicality, the module has been verified and practiced by a large number of chips.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eShipping list\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003ePhysical module+PDF schematic+after-sales technical support+electrostatic bag packaging+shockproof foam\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eReminder:\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e(1) The module interface of our store is clear and the performance is stable.

If it is consistent, it can be replaced.\u003c\/p\u003e\n\n\u003cp\u003eQ: What happens when the amplitude of input signal access module decreases?\u003c\/p\u003e\n\n\u003cp\u003eA: Generally, due to the impedance problem, the input impedance of high-speed operational amplifier is 50 Ω. If your signal output capacity is not enough, it will be pulled down.\u003c\/p\u003e\n\n\u003cp\u003eQ: The power supply of the module is normal, and there is a high-frequency sine wave output when there is no input?\u003c\/p\u003e\n\n\u003cp\u003eA: Because it is a high-speed amplifier, there may be self-excitation. You can try to adjust the potentiometer. Generally, self-excitation will not occur when the magnification is large.\u003c\/p\u003e\n\n\u003cp\u003e\u003cbr\u003e\n \u003c\/p\u003e\n","brand":"LOCKPICKWEB","offers":[{"title":"Default Title","offer_id":53231559541043,"sku":"THS4012 module","price":20.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0029\/6373\/4637\/files\/S46d8ef0730a1434f8000887bbb8e3eee8.webp?v=1776001058","url":"https:\/\/lockpickweb.com\/products\/ths4012-module-high-speed-operational-amplifier-290m-voltage-feedback-amplifier-2022ti-cup-electronic-competition","provider":"LOCKPICKWEB","version":"1.0","type":"link"}
