4 Channels 50pA 70 dB Instrumentational OP Amps 0.0002μA 7V~36V ±3.5V~18V LF347 14 Pins 14-SOIC (0.154, 3.90mm Width)
LF347DR Overview
There is a 14-SOIC (0.154, 3.90mm Width) case in which the instrumentation amplifier is packaged. Buffer amps of this type are called J-FET-types. A Tape & Reel (TR) case is used to deliver the buffer op amp. The number of terminations is approaching the 14 mark. The total number of pins on linear amplifier is 14. The linear amplifier should be run at 15V at all times, so please keep that in mind when using it. 14 pins are included on the operational amplifiers. As far as the input offset voltage is concerned, linear amplifier rates at 10mV. For this electronic part, it is recommended that you mount it with type 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 temperatureIt is possible to operate this buffer amplifier from a supply current of 8mA . 100dB should be the voltage gain. Op amp ic has 4 channels. For the packing of the instrumentation amplifier, TR is adopted.
