The input common-mode range extends to the negative rail, and the rail-to-rail output swings within millivolts of both rails.
The LMH6646MA/NOPB ships in a standard 8-SOIC (3.90 mm width) package, supplied in Tube. The ROHS3 compliance is current.
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.
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.
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.
