LMV2011MA

LMV2011MA Description

The LMV2011MA from Texas Instruments is a general-purpose operational amplifier designed for precision analog applications. Packaged in an 8-SOIC tube, this single-channel op-amp operates over a 2.7V to 5.25V supply range, making it suitable for low-voltage systems. With a 3 MHz gain bandwidth product (GBW) and a 4V/µs slew rate, it delivers stable performance for signal conditioning and amplification tasks. The device features an ultra-low input bias current of 3 pA and a minimal input offset voltage of 0.12 µV, ensuring high accuracy in sensitive circuits. Although marked as obsolete, its REACH-unaffected status and MSL 1 (Unlimited) moisture sensitivity level make it a reliable choice for existing designs.
