LM7301IMX Description

The LM7301IMX from Texas Instruments is a general-purpose operational amplifier (op-amp) designed for precision and low-power applications. Packaged in an 8-SOIC surface-mount configuration, this single-channel op-amp operates over a wide supply voltage range (1.8V to 32V), making it versatile for both low-voltage and industrial-level designs. With a gain bandwidth product (GBWP) of 4 MHz and a slew rate of 1.25V/µs, the LM7301IMX delivers stable performance in signal conditioning, filtering, and amplification tasks. Its low input bias current (103 nA) and minimal input offset voltage (40 µV) ensure high accuracy, while the low supply current (720 µA) enhances energy efficiency.
