The 3.3 mA per-channel supply current is the price you pay for that speed — this is not a micropower part, it is a signal-conditioning amp for ADC drivers, video buffers, or high-speed filter stages where bandwidth and settling time drive the choice.
Package and rework — the 8-DFN exposed pad
The 8-WFDFN exposed pad package (3x3 mm body) is a QFN-style part with a center thermal pad.
Fine for bench instruments, office equipment, audio gear, or indoor telecom — but do not spec it into a motor drive enclosure, engine bay, or outdoor cabinet without a temperature chamber test. The 450 µV input offset voltage is typical for a high-speed bipolar input stage; if you need sub-100 µV offset for precision DC, look at a chopper-stabilized amp instead.
