LF155AL Overview

Basic information of LF155AL amplifier:

LF155AL is an OPERATIONAL AMPLIFIER. The commonly used packaging method is LLCC-20

LF155AL amplifier core information:

The minimum operating temperature of LF155AL is -55 °C and the maximum operating temperature is 125 °C. Its peak reflow temperature is NOT SPECIFIED Its maximum bias current at 25°C is: 0.00005 µA Its maximum average bias current is 0.025 µA

How to simply check the efficiency of an amplifier? Looking at its slew rate, the nominal slew rate of LF155AL is 6 V/us. The manufacturer specifies a maximum slew rate of 4 mA for the LF155AL and a minimum slew rate of 3 V/us. Its minimum voltage gain is 25000. 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 LF155AL gain becomes 0.707 times the low-frequency gain is 6000 kHz.

The nominal supply voltage of LF155AL is 15 V, and its corresponding nominal negative supply voltage is -15 V. The power supply range is: +-15/+-20 V. The input offset voltage of LF155AL is 2500 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 LF155AL:

LF155AL has 20 terminals. Its terminal position type is: QUAD. Terminal pitch is 1.27 mm.

LF155AL amplifier additional information:

LF155AL 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 LF155AL is: YES. Its temperature grade is: MILITARY.

LF155AL is not Rohs certified. The corresponding JESD-30 code is: S-CQCC-N20. The corresponding JESD-609 code is: e0. The packaging code of LF155AL is: QCCN. The materials used in the LF155AL package are mostly CERAMIC, METAL-SEALED COFIRED.

The package shape is SQUARE. The LF155AL package pin form is: CHIP CARRIER. Its terminal forms are: NO LEAD.
