LM148FK Overview

Basic information of LM148FK amplifier:

LM148FK is an OPERATIONAL AMPLIFIER. Commonly used packaging methods are CERAMIC, LCC-20

LM148FK amplifier core information:

The minimum operating temperature of the LM148FK is -55 °C and the maximum operating temperature is 125 °C. Maximum bias current at 25°C: 0.1 µA Maximum average bias current is 0.325 µA

How to simply check the efficiency of an amplifier? Looking at its slew rate, the LM148FK has a nominal slew rate of 0.5 V/us. The maximum slew rate of the LM148FK given by the manufacturer is 3.6 mA. Its minimum voltage gain is 25000. 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 LM148FK gain becomes 0.707 times the low-frequency gain is 1000 kHz.

The nominal supply voltage of the LM148FK is 15 V, and its corresponding nominal negative supply voltage is -15 V. The input offset voltage of the LM148FK is 6000 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 LM148FK:

The width of LM148FK is: 8.89 mm, the length is 8.89 mm. LM148FK has 20 terminals. Its terminal position type is: QUAD. Terminal pitch is 1.27 mm. Total pins: 20

LM148FK amplifier additional information:

LM148FK adopts the VOLTAGE-FEEDBACK architecture. It does not belong to the low offset class of amplifiers. The frequency compensation status of LM148FK is: YES. Its temperature grade is: MILITARY. The corresponding JESD-30 code is: S-CQCC-N20.

The packaging code of LM148FK is: QCCN. The materials used in the LM148FK package are mostly CERAMIC, METAL-SEALED COFIRED. The package shape is SQUARE. The LM148FK package pin format is: CHIP CARRIER. Its terminal forms are: NO LEAD.

The maximum seat height is 2.03 mm.
