LM747EJ Overview

Basic information of LM747EJ amplifier:

LM747EJ is an OPERATIONAL AMPLIFIER. Commonly used packaging methods are DIP, DIP14,.3

LM747EJ amplifier core information:

The minimum operating temperature of the LM747EJ is and the maximum operating temperature is 70 °C. Its peak reflow temperature is NOT SPECIFIED Its maximum bias current at 25°C is: 0.08 µA Its maximum average bias current is 0.21 µA

How to simply check the efficiency of an amplifier? Looking at its slew rate, the LM747EJ has a nominal slew rate of 0.7 V/us. The manufacturer specifies a maximum slew rate of 5 mA for the LM747EJ and a minimum slew rate of 0.3 V/us. Its minimum voltage gain is 10000. When the op amp is used in a closed loop, at a certain closed-loop gain (usually 1 or 2, 10, etc.), the frequency when the LM747EJ gain becomes 0.707 times the low-frequency gain is 1500 kHz.

The nominal supply voltage of the LM747EJ is 20 V, and its corresponding nominal negative supply voltage is -20 V. The power supply range is: +-5/+-20 V. The input offset voltage of the LM747EJ is 4000 µV (input offset voltage: the compensation voltage added between the two input terminals to make the output terminal of the operational amplifier 0V (or close to 0V).)

Related dimensions of LM747EJ:

The width of LM747EJ is: 7.62 mm and the length is 19.304 mm. The LM747EJ has 14 terminals. Its terminal position type is: DUAL. Terminal pitch is 2.54 mm. Total pins: 14

LM747EJ amplifier additional information:

LM747EJ adopts the VOLTAGE-FEEDBACK architecture. It does not belong to the low offset class of amplifiers. The frequency compensation status of LM747EJ is: YES. Its temperature grade is: COMMERCIAL. The LM747EJ is not Rohs certified.

It contains lead. The corresponding JESD-30 code is: R-GDIP-T14. The corresponding JESD-609 code is: e0. The packaging code of LM747EJ is: DIP. The materials used in the LM747EJ package are mostly CERAMIC and GLASS-SEALED.

The package shape is RECTANGULAR. The LM747EJ package pin format is: IN-LINE. Its terminal form is: THROUGH-HOLE. The maximum seat height is 5.08 mm.
