1.5 MHz general-purpose op-amp in a SC-70-6 — what it fits
The Texas Instruments LMV981MG/NOPB is a single general-purpose op-amp with rail-to-rail output, a 1.5 MHz gain-bandwidth product, and a 0.42 V/µs slew rate. The SC-70-6 package keeps board area tight. Temperature range is -40°C to 125°C, so it handles industrial and automotive cabin environments without a grade split.
Supply range and quiescent current — battery-duty fit
At 116 µA supply current it stays on continuously in a battery-powered sensor node.
Rail-to-rail output and input offset — single-supply signal chain
Rail-to-rail output means the amplifier can swing within millivolts of the supply rails, which matters when the supply is only 1.8 V and every millivolt of headroom counts.
