55 MHz voltage-feedback op-amp with 22 V/µs slew rate
The Texas Instruments LMH6646MAX/NOPB is a dual-channel voltage-feedback operational amplifier in an 8-SOIC surface-mount package. 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
The LMH6646MAX/NOPB carries an Active lifecycle status from Texas Instruments and is ROHS3 compliant. There is no NRND or last-time-buy notice. For a procurement review, this means the part can be specified into new designs without an obsolescence watch window. 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.
Sourcing and availability
This part is sourced through independent distribution and quoted to order against an RFQ. For a BOM line that needs a dual high-speed op-amp in SOIC-8 with active lifecycle, submit an RFQ and the desk will return a firm price and lead-time window.
