It is packaged in an 8-TSSOP, 8-MSOP (0.118, 3.00mm Width)-case that protects the operational amplifiers from damage. There are two types of operational amplifiers in this circuit. A Tube case is used for delivering the op amp. Instrumentation amplifier is a part of Operational Amplifier. This electronic part is recommended for mounting type Surface Mount. According to the manufacturer, this buffer op amp works well at -40°C~125°C , which is a good operating temperature. A linear amplifier like this has 2 circuits on it. One of its many advantages is that buffer op amp outputs Rail-to-Rail signals. There is a recommendation that this electrical part be used with a supply with 2.2mA current rating.
