LMV358QDGKR

The Texas Instruments LMV358QDGKR is a dual operational amplifier from the LMV358 family, delivering rail-to-rail output drive and a 1-MHz unity-gain bandwidth optimized for low-voltage signal conditioning. Designed to operate from a single 2.7-V to 5.5-V supply, the device draws a quiescent current typically under 250 µA per channel and provides an output swing that extends to within a few millivolts of each rail, maximizing dynamic range in battery-powered and low-headroom designs. Its 8-pin VSSOP (MSOP) package offers a compact footprint suitable for space-constrained circuit layouts.

Typical applications span industrial sensor interfaces, active filter stages, data acquisition front ends, and portable instrumentation, where the combination of low power, rail-to-rail output, and 1-MHz bandwidth supports accurate signal amplification. The Q-suffix indicates AEC-Q100 automotive qualification, guaranteeing reliable performance across the -40°C to +125°C temperature range—a characteristic that also appeals to aerospace test equipment and defense subsystems requiring proven components without the specialty premium. For procurement planning, the LMV358QDGKR is an active, high-volume Texas Instruments part with well-established supply channels; this commercial-off-the-shelf availability minimizes obsolescence concerns while the automotive pedigree provides documented traceability and reliability metrics for demanding industrial and high-reliability programs.
