OPA121KM Overview

Basic information of OPA121KM amplifier:

OPA121KM is an OPERATIONAL AMPLIFIER from Texas Instruments. Commonly used packaging methods are HERMETIC, TO-99, 8 PIN

OPA121KM amplifier core information:

The minimum operating temperature of OPA121KM is and the maximum operating temperature is 70 °C. Its peak reflow temperature is NOT SPECIFIED Its maximum bias current at 25°C is: 0.000005 µA Its maximum average bias current is 0.000005 µA

How to simply check the efficiency of an amplifier? Looking at its slew rate, the OPA121KM has a nominal slew rate of 32 V/us. The maximum slew rate of OPA121KM given by the manufacturer is 4.5 mA. Its minimum voltage gain is 200000. 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 OPA121KM gain becomes 0.707 times the low-frequency gain is 2000 kHz.

The nominal supply voltage of OPA121KM is 15 V, and its corresponding nominal negative supply voltage is -15 V. The input offset voltage of the OPA121KM is 2000 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 OPA121KM:

OPA121KM has 8 terminals. Its terminal position type is: BOTTOM. Total pins: 8

OPA121KM amplifier additional information:

OPA121KM 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 OPA121KM is: YES. Its temperature grade is: COMMERCIAL.

OPA121KM is not Rohs certified. It contains lead. The corresponding JESD-30 code is: O-MBCY-W8. The package code of OPA121KM is: TO-99. The materials used in the OPA121KM package are mostly METAL.

And its package shape is ROUND. The OPA121KM package pin format is: CYLINDRICAL. Its terminal form is: WIRE.
