LM148FKB Product Details

LM148FKB Overview


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 20. Linear amplifier has a total of 20 pins. Please take in mind that op amp should be run at 15V. Instrumentation amplifier is a part of Operational Amplifier. Linear amplifier includes 20 pins. Regarding input offset voltage, buffer amplifier rates 5mV voltage. The voltage gain should stay at 104.08dB. Instrumentation amplifier has 4 channels on it. It should not lower than -55°C to operate buffer amplifier. It is recommended that op amp be used at temperatures below 125°C. With regard tp supply voltage, op amp is used under 18V. Conduct linear amplifier under the dual suuply voltage of 18V.
