Baby name:OPA627Amplifier module

Baby size:X 36mm 50mm

Baby power:OPA627(.4.5..MAX 18V)(default TI chip)

 

Description: this shop produced following the dual operational amplifier, single operational amplifier and re designed a single operational amplifier module, this modulePCBBoard compatibility is extremely strong, basically apply to the majority of the marketSOP8Series of single chip, the use of very convenient. We use the materials are very high quality and convenient, such as input and output signals are used in high frequency coaxial cable connector, can reduce the loss of signal amplitude and interference shielding other signals, at the same time onboard amplifier can meet the needs of users will change (random function1Can be changed into the same phase amplifier;2Can be changed to reverse amplifier;3Can be changed to shoot with the output;4Can be converted into an integrated amplifier;5(can be changed to a differential amplifier), we use two gain mode to the user1Direct resistor fixed magnification;2Manual amplification of high quality sliding variable design. The board has a high quality of the capacitor filter and excellentPCBLayout and walk the line, the owner of the design of thisPCBBoards are more compatible with the RF class of single transport, in the line and design above all in accordance with the RF requirements to do, of course, low frequency signal is also very good. So in terms of function, or in the practicability of the above, are only after a lot of practice module to create such a baby, hope that the majority of users a lot of attention. Conway electronics provides bulk supply, according to customer requirements and design index of debugging, ultimately determine the index after delivery. Pay attention to our attention, Conway Electronic Science and technology, we are working on the modular road. Conway electronic staff are willing to serve you, your design will become more simple.
