Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'M7' against the manufacturer's official orderable addendum to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS standards if required by your manufacturing process. Confirm that the commercial grade temperature rating aligns with your system requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when space efficiency and low power consumption are critical constraints. It serves as a low-voltage alternative to standard 5 V to 30 V op amps. Consider its bipolar input stage for improved noise performance and higher output current drive compared to CMOS alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LMV3xx-N family, which includes dual (LMV358) and quad (LMV324) variants. These amplifiers are designed as low-voltage versions of commodity op amps like the LM358 and LM324. The family utilizes an advanced submicron silicon-gate BiCMOS process to achieve excellent speed-to-power ratios.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LMV321M7 support negative input voltages?

The input common-mode voltage range extends to -0.2 V relative to the negative supply. Protection should be provided to prevent input voltages from exceeding -0.3 V.

What is the capacitive load tolerance of this amplifier?

The device can directly drive up to 200 pF in a unity-gain configuration without oscillation. Heavier loads require resistive isolation for stability.
