LM124FKB Product Details

LM124FKB Overview


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 Rail/Tube case. It is estimated that there will be at least 20 terminations this year. A total of 20 pins are attached to buffer op amp. As a reminder, this buffer op amp should be powered by 5V battery and that the battery should be inserted in the amplifier. A type of Operational Amplifier op amp ic can be identified by the fact that this is a type of Operational Amplifier device. In total, the buffer amplifier consists of 20 pins. Op amp ic rates 5mV for input offset voltage. 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 -55°C degrees Celsius. You should only use op amp buffer at temperatures that are no higher than 125°C. It is important to keep in mind that the power supply voltage of this electric component is below 32V, which is suitable. Keeping the linear amplifier's supply voltage above 3V is recommended. In order to conduct this part, you will need to provide dual supply voltages of 16V volts.
