Product details

Supply range and single-supply operation

The part operates from a single supply between 2.5 V and 12 V. The input common-mode range extends to the negative rail, and the rail-to-rail output swings within millivolts of both rails.

Package and sourcing reality

The LMH6646MA/NOPB ships in a standard 8-SOIC (3.90 mm width) package, supplied in Tube. TI's lifecycle status is Active — no end-of-life notice, no last-time-buy window. The ROHS3 compliance is current. Sourced through independent distribution, availability and pricing are confirmed at quote time.

Frequently asked questions

What is the difference between LMH6646MA and LMH6646MA/NOPB?

The /NOPB suffix indicates a lead-free (no Pb) finish, which is TI's standard green packaging. The LMH6646MA (without suffix) may have a tin-lead finish. Both are electrically identical, but the /NOPB variant is ROHS3 compliant.

Is LMH6646MA/NOPB suitable for single supply operation?

Yes. It operates from a single supply between 2.5 V and 12 V, with rail-to-rail output swing that maximizes dynamic range on low-voltage rails.

What is the closest functional equivalent to LMH6646MA/NOPB?

For a dual-channel voltage-feedback op-amp with similar speed, the TLV9362IDDFR offers 10.6 MHz bandwidth and 25 V/µs slew rate in a different package. The OPA4374AIPWT is a quad CMOS alternative but slower at 6.5 MHz and 5 V/µs — not a direct speed match.
