Package and mounting
The LMV821M5X: Quiescent current sits at 300 µA per channel — not the lowest for a battery node, but reasonable for a powered-up sensor interface or a control-loop filter where you want the bandwidth without burning through the LDO budget.
SOT-23-5 footprint — the scorch mark tells you
The package is a 5-pin SOT-23-5 (SC-74A, SOT-753), surface-mount only. That five-pin SOT-23 is a common footprint for single op-amps — if you're swapping one on a board that came back from the field, the scorch mark around the output pin is usually the tell. The 45 mA output drive per channel is enough to swing a 10 kΩ load rail-to-rail or drive the ADC input of a typical automotive MCU without a separate buffer.
AEC-Q100 and active lifecycle — no LTB math needed
It's also AEC-Q100 qualified, which means the wafer fab and assembly line have the automotive-grade process controls and the part has passed the stress tests (high-temperature operating life, temperature cycling, ESD) that the commercial-grade sibling skips.
