LM1458H Product Details

LM1458H Overview


Packaged in a TO-5 case, the buffer op amp is ready to use. An op amp ic of the OPERATIONAL AMPLIFIER type. There is a growing number of terminations approaching the number of 8. I would like to remind you that this buffer op amp should be powered by an 15V battery. A total of 8 pins are present on the instrumentation amplifier. There is an input offset voltage of 6mV for this buffer op amp. 104.08dB should remain the voltage gain. During the manufacturing process, this buffer amplifier is divided into 2 circuits. For the buffer op amp to operate properly, it must be above the temperature of 0°C degrees Celsius. No temperature greater than 70°C should be used. As a rule of thumb, you should conduct this electronic part under a dual voltage supply of 18V volts.
