Description
LMV358B-VR is a TI dual operational amplifier in the LMV358 family. It’s built for low-voltage, single-supply operation (typically 2.7–5.5 V) with rail-to-rail input and output, making it suitable for battery-powered and sensor-front-end apps. The “B” grade indicates improved offset/bias performance and temperature characteristics over the base device. It is unity-gain stable and offers low quiescent current per amplifier, suitable for compact, low-power analog circuits. The “VR” suffix usually denotes a variant in a tape-and-reel or specific packaging option for surface-mount devices.
Common uses include buffering, active filtering, signal conditioning, and small-signal amplification in portable electronics, instrumentation, and consumer/industrial sensors.
Packages: typically 8-pin packages (SOIC/MSOP) with VR packaging variants; check the datasheet for exact package types and electrical specs such as input offset, bias current, gain-bandwidth, and slew rate. Always refer to the TI datasheet for precise values and packaging details.
