LF347DRE4 Product Details

LF347DRE4 Overview


It is packaged in an SOIC-case that protects the operational amplifiers from damage. An op amp of this type is a OPERATIONAL AMPLIFIER-type. As far as the packaging is concerned, buffer op amp is delivered in a Tape & Reel case. It is estimated that there will be at least 14 terminations this year. 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 total, the buffer amplifier consists of 14 pins. Op amp ic rates 5mV for input offset voltage. A supply current of 8mA can be used to operate this linear amplifier. There should be no change in the voltage gain at 100dB. There are a total of 4 channels available on the op amps. This instrumentation amplifier cannot operate below 0°C degrees Celsius. You should only use op amp buffer at temperatures that are no higher than 70°C. The operating supply voltage of the buffer op amp is rated at 18V. An buffer amplifier is packed in a TAPE AND REEL-shape according to the design. In order to conduct this part, you will need to provide dual supply voltages of 18V volts.
