It runs on a single supply from 2.5 V to 12 V and draws just 725 µA quiescent current — a combination that makes it a natural fit for battery-powered or portable signal-conditioning chains where every microamp counts. The rail-to-rail output swing means you keep the full dynamic range when driving an ADC input or a low-voltage signal path. Typical applications include sensor amplifiers, active filters, and ADC buffer stages in industrial control, test equipment, and portable instrumentation where the ambient temperature stays within -40°C to 85°C. ## Key ratings and what they mean on the bench The 55 MHz -3dB bandwidth and 22 V/µs slew rate define the small-signal and large-signal speed.","metaTitle":"TI LMH6645MF/NOPB Voltage Feedback Op-Amp, 55 MHz, SOT-23-5","metaDescription":"TI LMH6645MF/NOPB voltage feedback op-amp, 55 MHz -3dB bandwidth, 22 V/µs slew rate, rail-to-rail output, 725 µA supply, SOT-23-5.

Both share the same VIP10™ series core specs (55 MHz bandwidth, 22 V/µs slew rate, rail-to-rail output, 725 µA per channel supply). The pinout differs because the LMH6646 has two channels."},{"question":"Can LMH6645MF/NOPB be used as a comparator?","answer":"It is a voltage-feedback op-amp, not a comparator. While it can be pressed into comparator service at low speed, the output stage is not designed for open-loop saturation recovery — expect longer propagation delay and possible phase reversal. A dedicated comparator like the TLV3501 is a better choice for that role."},{"question":"What is the exact pinout of LMH6645MF/NOPB?","answer":"The SOT-23-5 (SC-74A) pinout is standard: pin 1 = output, pin 2 = V-, pin 3 = non-inverting input, pin 4 = inverting input, pin 5 = V+.
