LF347N/PB Product Details

LF347N/PB Overview


The linear amplifier is packaged in a 14-DIP (0.300, 7.62mm) case which makes it easy for the consumer to handle. Buffer amps of this type are called J-FET-types. The case in which buffer amplifier is delivered is called a Tube case. It is estimated that there will be at least 14 terminations this year. It consists of a total of 14 pins in total. I would like you to keep in mind that this buffer amplifier needs to be run at a voltage of 15V. Instrumentation amplifier is a part of Operational Amplifier. Linear amplifier includes 14 pins. Regarding input offset voltage, buffer amplifier rates 10mV voltage. The mounting type that is recommended for this electrical part is Through Hole. According to the manufacturer, this buffer op amp works well at 0°C~70°C , which is a good operating temperature. There should be no change in the voltage gain. This op amp contains 4 circuits. A voltage rating of 4 is indicated for the op amp's operating supply voltage. The operating supply voltage of the buffer op amp is rated at 18V. This buffer amplifier is assigned within the BI-FET II? series by its manufacturer.
