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.","metaTitle":"TI LMH6646MA/NOPB Dual Voltage Feedback Op-Amp, 55 MHz","metaDescription":"TI LMH6646MA/NOPB dual voltage-feedback op-amp in 8-SOIC. 55 MHz bandwidth, 22V/µs slew rate, rail-to-rail output, 725µA per channel supply.

The LMH6646MA (without suffix) may have a tin-lead finish. Both are electrically identical, but the /NOPB variant is ROHS3 compliant."},{"question":"Is LMH6646MA/NOPB suitable for single supply operation?","answer":"Yes.
