LF157GC Overview

Basic information of LF157GC amplifier:

LF157GC is an OPERATIONAL AMPLIFIER. The commonly used packaging method is LCC-20

LF157GC amplifier core information:

The minimum operating temperature of the LF157GC 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 0.05 µA

How to simply check the efficiency of an amplifier? Looking at its slew rate, the nominal slew rate of LF157GC is 50 V/us. The manufacturer specifies a maximum slew rate of 7 mA for the LF157GC and a minimum slew rate of 30 V/us. 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 LF157GC gain becomes 0.707 times the low-frequency gain is 20,000 kHz.

The nominal supply voltage of the LF157GC is 15 V, and its corresponding nominal negative supply voltage is -15 V. The input offset voltage of the LF157GC is 7000 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 LF157GC:

LF157GC has 20 terminals. Its terminal position type is: QUAD. Terminal pitch is 1.27 mm. Total pins: 20

LF157GC amplifier additional information:

LF157GC 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 LF157GC is: YES (AVCL>=5). Its temperature grade is: MILITARY.

LF157GC is not Rohs certified. The corresponding JESD-30 code is: S-CQCC-N20. The corresponding JESD-609 code is: e0. The packaging code of LF157GC is: QCCN. The materials used in the LF157GC package are mostly CERAMIC, METAL-SEALED COFIRED.

The package shape is SQUARE. The LF157GC package pin format is: CHIP CARRIER. Its terminal forms are: NO LEAD.
