LT1639IS Product Details

LT1639IS Overview


A 14-SOIC (0.154, 3.90mm Width) case is used to package the op amp. General Purpose-type instrumentation amplifiers are used in this application. The case in which buffer amplifier is delivered is called a Tube case. It is estimated that there will be 14 terminations in the next few months. There are a total of 14 pins on this op amp. It is important to remember that this op amp should be operated at a voltage of 15V volts. It should be noted that this op amp is a type of Operational Amplifier device. It is recommended that this electronic component be mounted using the Surface Mount mounting type. In terms of operating temperature, this instrumentation amplifier performs well at a temperature of about -40°C~85°C . On this instrumentation amplifier, there are 4 circuits that are connected together. One of the advantages of this op amp is that it outputs Rail-to-Rail signals, which is one of its many advantages. As a recommendation, this electronic component should be used with a power supply that can deliver 205μA. The Over-The-Top® indicates the series number of the op amp. There is a minimum voltage gain of 100000 that this buffer op amp is capable of conducting.
