In order to protect the op amps, a 8-SOIC (0.154, 3.90mm Width) case is used. A General Purpose-type buffer amplifier is shown here. The op amp is delivered to you in a Tape & Reel (TR) case. It is estimated that there will be 8 terminations in the next few months. It consists of a total of 8 pins in total. As a reminder, this buffer op amp should be powered by 15V battery and that the battery should be inserted in the amplifier. In order to be more specific, this instrumentation amplifier is one of the types of Operational Amplifier devices. Linear amplifier includes 8 pins. Regarding input offset voltage, buffer amplifier rates 25μV voltage. This electrical part should be mounted using type Surface Mount. According to the manufacturer, this buffer op amp works well at -40°C~85°C , which is a good operating temperature. Using an 790μA supply current, this operational amplifier ics can be operated. You should keep the voltage gain at 140dB for the time being. This linear amplifier has a total of 2 elements. For the packing of the instrumentation amplifier, TR is adopted.
