KF347 Overview

Basic information about KF347 amplifier:

KF347 is an OPERATIONAL AMPLIFIER. Commonly used packaging methods are 0.300 INCH, DIP-14

KF347 amplifier core information:

The minimum operating temperature of KF347 is and the maximum operating temperature is 70 °C. Its peak reflow temperature is NOT SPECIFIED. Its maximum bias current at 25°C is: 0.0002 µA. Its maximum average bias current is 0.000008 µA and its maximum input offset current (IIO) is only 0.004 µA.

How to simply check the efficiency of an amplifier? Looking at its slew rate, the KF347 has a nominal slew rate of 13 V/us. The maximum slew rate of the KF347 given by the manufacturer is 11 mA. Its minimum voltage gain is 15000. When the op amp is used in closed loop, at a certain closed-loop gain (usually 1 or 2, 10, etc.), the frequency when the KF347 gain becomes 0.707 times the low-frequency gain is 4000 kHz.

The nominal supply voltage of KF347 is 15 V, and its corresponding nominal negative supply voltage is -15 V. The input offset voltage of KF347 is 13000 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 KF347:

The width of KF347 is: 7.62 mm and the length is 19.4 mm. KF347 has 14 terminals. Its terminal position type is: DUAL. Terminal pitch is 2.54 mm. Total pins: 14

KF347 amplifier additional information:

KF347 adopts the VOLTAGE-FEEDBACK architecture. It belongs to the low-bias class of amplifiers. It does not belong to the low offset class of amplifiers. The frequency compensation status of KF347 is: YES. Its temperature grade is: COMMERCIAL.

KF347 is not Rohs certified. It contains lead. The corresponding JESD-30 code is: R-PDIP-T14. The corresponding JESD-609 code is: e0. The packaging code of KF347 is: DIP.

The materials used in KF347 packaging are mostly PLASTIC/EPOXY. The package shape is RECTANGULAR. The KF347 package pin format is: IN-LINE. Its terminal form is: THROUGH-HOLE. The maximum seat height is 5.08 mm.
