LM139AJB Overview

It is packaged in an CDIP-case that protects the operational amplifiers from damage. An op amp of this type is a COMPARATOR-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 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 5V battery and that the battery should be inserted in the amplifier. In total, the buffer amplifier consists of 14 pins. Op amp ic rates 2mV for input offset voltage. This electronic part is recommended for mounting type Through Hole. In terms of operating temperature, this instrumentation amplifier is well suited to a temperature range of -55°C ~ 125°C. There should be no change in the voltage gain at 106.02dB. There are a total of 4 channels available on the op amps. One of its many advantages is that buffer op amp outputs OPEN-COLLECTOR signals. 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. There are 4 elements in this buffer amplifier. It is important to keep in mind that the power supply voltage of this electric component is below 36V, which is suitable. Keeping the linear amplifier's supply voltage above 2V is recommended. In order to conduct this part, you will need to provide dual supply voltages of 18V volts. Buffer op amp series numbers are indicated by the -.
