Single-supply voltage feedback amp with rail-to-rail output
The TI LMH6645MAX/NOPB is a single-channel voltage feedback op-amp from the VIP10™ series, packaged in an 8-SOIC. 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.
