LF347DG4 Product Details

LF347DG4 Overview


Op amp is packaged in SOIC case. Op amps are OPERATIONAL AMPLIFIER types of amplifier on the chip. Instrumentation amplifier is delivered in a Rail/Tube case. The number of terminations approaches 14. Linear amplifier has a total of 14 pins. Please take in mind that op amp should be run at 15V. Instrumentation amplifier is a part of Operational Amplifier. Linear amplifier includes 14 pins. Regarding input offset voltage, buffer amplifier rates 10mV voltage. Operational amplifier can operate supply current at 8mA. The voltage gain should stay at 100dB. It should not lower than 0°C to operate buffer amplifier. It is recommended that op amp be used at temperatures below 70°C. Op amp has total of 4 elements. The operating supply voltage of instrumentation amplifier is rated 18V voltage. Conduct linear amplifier under the dual suuply voltage of 18V.
