LF444CM/NOPB Overview


Packaged in a 14-SOIC (0.154, 3.90mm Width) case, the buffer op amp is ready to use. J-FET-type instrumentation amplifiers are used in this application. Upon delivery, op amp ic is packaged in a Tube case. It is estimated that there will be 14 terminations in the next few months. A total of 14 pins are attached to buffer op amp. 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. 14 pins are located on the operational amplifiers. As far as the input offset voltage is concerned, linear amplifier rates at 3mV. The mounting type that is recommended for this electrical part is Surface Mount. It is important to note that this linear amplifier works well at a temperature of 0°C~70°C when it comes to operating temperatureAn 600μA volt supply current is needed for this linear amplifier to operate. You should keep the voltage gain at 100dB for the time being. 4 channels are available on the instrumentation amplifier. The operating supply voltage of the buffer op amp is rated at 18V. Buffer op amp series numbers are indicated by the BI-FET?.
