What this op-amp is and where it fits
The STMicroelectronics LMV821AILT is a single-channel general-purpose operational amplifier with rail-to-rail output, packaged in a SOT-23-5. It delivers a gain-bandwidth product of 5.5 MHz and a slew rate of 1.9 V/µs, drawing 300 µA of supply current. The supply span runs from 2.5 V to 5.5 V. With an operating temperature range of -40°C to 125°C, it is rated for industrial and automotive under-hood environments.
5.5 MHz GBW and 1.9 V/µs slew — what they mean for the loop
The 5.5 MHz gain-bandwidth product sets the usable closed-loop bandwidth for small-signal conditioning. The 1.9 V/µs slew rate supports full-output swings without slew-induced distortion. For a rail-to-rail output rated at 70 mA, the part can drive moderate loads.
Active lifecycle — no LTB pressure
The LMV821AILT carries an Active product status and is ROHS3 compliant. There is no last-time-buy notice or end-of-life signal on this line. For a BOM line that needs a stable single-supply op-amp in a small footprint, this part is safe to qualify into production without near-term obsolescence risk.
