That combination — wide bandwidth and low quiescent — makes it a fit for battery-operated signal chains where you need to condition a fast sensor signal or drive a SAR ADC input without burning through the battery budget.
725 µA supply — counting the microamps
At 725 µA supply current, this op-amp sits in a power-bandwidth sweet spot. A typical general-purpose rail-to-rail op-amp at 55 MHz might pull 2 mA or more; the LMH6647 keeps the draw under a milliamp. For a LoRa or Zigbee sensor node running on a CR2032, that extra 1.3 mA saved per amplifier directly extends the sleep-to-wake cycle budget. The 20 mA output drive per channel is enough to swing a 2 Vpp signal into a 100 Ω load or drive the reference input of a successive-approximation ADC.
Rated for a supply span of 2.5 V to 12 V, the part runs from a single Li-ion cell (3.0 V to 4.2 V) up to a regulated 12 V industrial rail. Input offset voltage is specified at 1 mV, input bias current at 650 nA, both typical values for a voltage-feedback topology in this speed class.
Package and footprint
The supplier device package is 8-SOIC — no exposed pad, no thermal-via stitch needed at the 725 µA quiescent level. The listed shipping medium is Bulk, so expect it in tubes or trays rather than tape-and-reel; factor that into your pick-and-place feeder setup if you are ordering production quantities.
