It delivers a -3dB bandwidth of 55 MHz and a slew rate of 22 V/µs while drawing only 725 µA of supply current — a useful balance for applications that need moderate speed without burning through the power budget. The push-pull rail-to-rail output stage maintains signal swing close to the supply rails, which matters when running from a 2.5 V rail where every millivolt of headroom counts. Typical uses include video buffering, ADC driver stages, and active filters in portable or industrial equipment where the -40°C to 85°C temperature range covers most indoor and outdoor enclosures. ## Supply range and output drive — what they mean for the BOM The supply span runs from 2.5 V to 12 V. Output current is rated at 20 mA per channel. The 1 mV input offset voltage and 650 nA input bias current are typical for a bipolar-input voltage-feedback amp at this speed. ## Sourcing and fit for production This part is sourced through independent distribution and quoted to order against an RFQ. The 8-SOIC footprint is a standard, widely supported package.","metaTitle":"TI LMH6645MAX/NOPB Voltage Feedback Op-Amp, 55 MHz, 22V/µs","metaDescription":"TI LMH6645MAX/NOPB voltage feedback op-amp: 55 MHz -3dB bandwidth, 22V/µs slew rate, rail-to-rail output, 2.5-12V supply.

The OPA4374AIPWT is a quad CMOS rail-to-rail amp with lower bandwidth (6.5 MHz) and much lower input bias current (0.5 pA), but it is a different circuit count and architecture.
