LM346M Product Details

LM346M Overview


The linear amplifier is packaged in a 16-SOIC (0.154, 3.90mm Width) case. A General Purpose-type buffer amplifier is shown here. A Tube case is used for delivering the op amp. A total of 16 terminations have been reported in the past few weeks. It consists of a total of 16 pins in total. Please take in mind that this instrumentation amplifier should be run at 15V. It should be noted that this type of buffer amplifier is exactly what is known as a Operational Amplifier device. 16 pins are included on the operational amplifiers. With regards to the offset voltage of the input, buffer amplifier is rated at 500μV. For this electrical component, Surface Mount is the recommended mounting type. The buffer amplifier functions well at 0°C~70°C as far as operating temperature is concerned. Using an 1.4mA supply current, this operational amplifier ics can be operated. It is a member of the 120dB's 120dB family. As far as the device is concerned, buffer amplifier has 4 channels. The operating supply voltage of instrumentation amplifier is rated 18V voltage.
