Product details

Quad CMOS op-amp for multi-channel signal chains

The Texas Instruments LMV344MA/NOPB is a CMOS rail-to-rail output operational amplifier with four independent circuits in a 14-SOIC package.

Supply current and battery-life trade-off

At 107 µA per channel, the total quiescent draw for all four amplifiers is 428 µA. In a 3.7 V Li-ion system that translates to roughly 1.6 mW quiescent — low enough that the op-amp itself is not the dominant drain in a microcontroller-centric design. The 0.02 pA input bias current also preserves accuracy when using high-impedance sensor bridges without a buffer stage.

The NOPB suffix confirms lead-free / RoHS3-compliant finish.

Frequently asked questions

Is LMV344MA/NOPB suitable for battery-powered applications?

Yes. The 107 µA per-channel supply current and 2.7 V minimum supply voltage make it a good fit for 3.3 V or 3.7 V battery-powered sensor interfaces. The rail-to-rail output also preserves dynamic range at low supply voltages.

Are there any direct replacements for LMV344MA/NOPB?

A close functional peer is the OPA4374AIPWT — also a quad CMOS rail-to-rail op-amp in a surface-mount package, with a 6.5 MHz gain-bandwidth and 5 V/µs slew rate. The OPA4374 draws 600 µA per channel, so the LMV344MA is the lower-power choice. Verify the package and pinout compatibility for your layout before substituting.
