Product details

55 MHz voltage-feedback op-amp with 22 V/µs slew rate

It delivers a 55 MHz -3dB bandwidth and a 22 V/µs slew rate while drawing 725 µA per channel. The rail-to-rail output stage (push-pull) swings close to the supply rails. Supply span runs from 2.5 V to 12 V. Operating temperature is -40°C to 85°C.

Active production — no lifecycle risk for new BOMs

There is no NRND or last-time-buy notice. The NOPB suffix confirms lead-free (RoHS) construction. If you are qualifying an alternate for dual-source coverage, the TLV9362IDDFR (dual, 10.6 MHz, 25 V/µs) is a functional peer in the same package footprint — but verify pinout compatibility against your layout.

Frequently asked questions

Is LMH6646MAX/NOPB rail-to-rail output?

Yes, the output type is push-pull, rail-to-rail, allowing the output to swing close to both supply rails — useful in single-supply systems where headroom is limited.

What is the closest functional equivalent for LMH6646MAX/NOPB?

The TLV9362IDDFR is a dual general-purpose op-amp with 10.6 MHz bandwidth, 25 V/µs slew rate, and rail-to-rail output in a similar package. It is a functional peer but verify pinout compatibility before substitution.
